    Notes: Abstract LaNi1−x FexO3 (x = 0, 0.25, 0.5) has been synthesized by the hydroxide solid solution precursor method for electrochemical characterization as oxygen anode in strongly alkaline medium. Studies were made at the oxide film, which was obtained by the oxide-slurry painting technique. The cyclic voltammetric study showed the formation of a diffusion-controlled quasireversible redox couple, Ni(ii)/Ni(iii), (E 0 ∼- 430 ± 10 mV) at the oxide surface in 1 m KOH. The reaction was observed to follow approximately first-order kinetics in OH− concentration. Values of the Tafel slope ranged between 59 and 86 mV decade−1 with all the oxide film electrodes. The electrocatalytic activity was found to be greatest with the Ni/LaNi0.75Fe0.25O3 electrode. A comparison was made between the electrocatalytic activities of LaNiO3 prepared by the hydroxide solid solution precursor and by the hydroxide coprecipitation technique.

    Notes: Abstract From a systematic analysis of the available balloon data for searching variabilities in the time-scales of days for Cyg X-1, the first evidence for the existence of a distinct phase dependence of intensity at 30 keV, corresponding to a period of 5.6 days, is presented. Additionally, the existence of a two-state X-ray emission at these energies is also indicated. Implications of these variabilities on the existing models of Cyg X-1 are discussed.

    Notes: Abstract The paper presents the results of the investigation on the short term X-ray emission characteristics of Cyg X-1 in the 20–150 keV range. The observations were made with balloon-borne oriented scintillation telescope and the flights were conducted from Hyderabad, India. The source was tracked over a duration of 1 hr that enabled detailed observations with time resolution of the order of 1 min. Fluctuations in the intensity of Cyg X-1 with time scales of the order of minutes have been detected besides short-term flare-like enhancements. The spectral characteristics of the flare emission features are discussed and their relationship to the phase of the binary is examined.

    Strongly coupled bands as “effectively” decoupled bands (1984)
    Springer

    ISSN: 1434-601X

    Topics: Physics
    Notes: Abstract We present experimental evidence which suggests that almost all the strongly coupled bands in the rare-earth region may also be treated as “effectively” decoupled bands. In contrast to the usual decoupled bands, the strongly coupled bands seem to arise from a system where a particle carrying an “effective” angular momentumj′ is aligned to an even-even core having an “effective” rotational angular momentumR′ which is not necessarily zero for the band head but may even haveR′=2 or, 4 or, 6⋯etc. We attempt to explain these observations in a simple physical picture whereinJ R, the projection ofj, the particle angular momentum, on the rotation axis, is taken as the effectively aligned spin of the last particle. Preliminary results from schematic bandmixing calculations forh 9/2 andf 5/2 orbitals with the Fermi energy lying near the highK single particle levels indeed reveal the existence of “effectively” decoupled bands which seem to agree with this physical picture.

    Description / Table of Contents: Abstract The Garhwal Lesser Himalayan Krol Belt contains two well developed diamictite horizons in the Late Palaeozoic Blaini Formation. Structureless and massive diamictites contain clasts of different shape, roundness and lithologies comprising mainly shale, slate, phyllite, quartzite, vein quartz and limestone dispersed in fine sandy argillaceous and calcareous matrix. Clast composition and petrography of the diamictites and other lithologies of the Blaini Formation reveal the presence of sedimentary and low grade metamorphic rocks in the provenance of the Blaini. The provenance seems to be the Lesser Himalayan terrain of the Simla Slate, Jaunsar and Shali-Deoban carbonates which had probably undergone structural deformation prior to the Late Palaeozoic. Two glacier advances deposited the diamictites near the shoreline of the Krol Basin during Late Palaeozoic.
    Abstract: Résumé Dans la ceinture de Krol de l'Himalaya mineur, la Formation de Blaini, d'âge Paléozoique supérieur, renferme deux horizons à diamictites sédimentaires. Celles-ci, massives et sans structure interne, contiennent des éléments clastiques de forme arrondi et lithologie différents; ce sont des schistes métamorphiques, des phyllites, des quartzites, du quartz-filonien et des calcaires disposés dans une matrice fine, argilosableuse avec participation carbonatée. La composition des éléments clastiques et la pétrographie des diamictites, comme celles des autres roches de la Formation de Blaini, montrent la présence de roches sédimentaires et de roches faiblement métamorphiques de même provenance que la formation de Blaini; cette provenance peut comprendre les schistes de Simla et les roches carbonatées de Jaunsar et de Shali-Deoban qui furent métamorphisées probablement avant le Paléozoique supérieur. C'est au cours de deux avancées glaciaires que les diamictites ont été déposées en bordure du bassin de Krol pendant le Paléozoique supérieur.
    Notes: Zusammenfassung Im Krol Belt des Kleinen Himalaya sind in der jungpaläozoischen Blaini-Formation zwei Horizonte mit sedimentären Diamictiten enthalten. Die strukturlosen und massiven Diamictite enthalten Klastika verschiedener Form, Rundung und Lithologie. So findet man Schiefer, Phyllite, Quarzite, Gangquarze und Kalke in einer feinsandigen, tonigen Matrix mit Karbonatanteilen. Die Zusammensetzung der Klaste und die Petrographie der Diamictite sowie der übrigen Gesteine der Blaini-Formation zeigen die Anwesenheit von Sedimentgesteinen und schwach metamorphisierten Gesteinen im Einzugsbereich der Blaini-Formation. Dieser Bereich kann die Simla-Schiefer und die Jaunsar- und Shali-Deoban-Karbonate des Kleinen Himalaya mit umfassen, die vermutlich vorjungpaläozoisch metamorphisiert wurden. Während zweier Gletschervorstöße sind die Diamictite randlich im Krol-Becken während des Jungpaläozoikums abgelagert worden.

    Description / Table of Contents: Abstract In the Lesser Himalayan region of Garhwal, an elongate, NW-SE trending zone of mylonitic rocks is developed along the Singuni Thrust within the metasedimentary formation of the Deoban-Tejam Belt. Detailed petrography of various mylonitic rocks indicates that a quartz and felspar porphyry was emplaced along the Singuni Thrust. This was initially metamorphosed in the almandine-amphibolite facies before profound ruptural or cataclastic and crystalloblastic deformation evolved mylonitic rocks in the green schist facies. Southwesterly dipping foliation and an equally prominent mica lineation plunging in the same direction are developed in these mylonitic rocks. The quartzite is also intensely cataclastically deformed in the green schist facies and is highly schistose with a prominent mica lineation normal to the trace of Singuni Thrust, Uttarkashi Thrust and Main Central Thrust in the ‘a’ direction of tectonic transport. In quartzite and mylonitic rocks, a probable contemporaneous development of the metamorphic and structural elements has been postulated along the Singuni Thrust during large scale tectonic movements. Normally exposed Gamri Quartzite is more metamorphosed near its base along the Singuni Thrust and Uttarkashi Thrust while the intensity of deformation increases near the top of normally exposed quartzite along the Main Central Thrust and, thus, signifying the role of thrusting in cataclastically deforming the rocks and contributing to the phenomenon of widespread reversal of metamorphism in the Lesser Himalaya.
    Abstract: Résumé Dans la région de Garhwale (Himalaya inférieur), une zone des roches mylonitiques allongée et orientée Nord-Ouest-Sud-Est se développe le long du chevauchement Singuni dans des formations métasédimentaires de la zone Déobane—Téjame. Une étude pétrographique détaillée de ces roches mylonitiques montre qu'un porphyre à quartz et feldspath s'est mis en place le long du chevauchement Singuni. Il fut au début métamorphosé dans le facies Almandin-Amphibolite avant qu'une déformation rupturale profonde ou une déformation cataclastique et crystalloblastique n'en fasse une roche mylonitique du facies Schiste-vert. Une foliation plongeant au Sud-Ouest et une linéation de Mica aussi importante plongeant dans la mÊme direction, se sont développées dans ces roches mylonitiques. Le quartzite est aussi intensément déformé de manière cataclastique dans le facies Schistevert et fortement schistifié avec une linéation de Mica bien nette, perpendiculaire à l'allure des chevauchements Singuni, Uttarkashi et du Grund chevauchement Central dans la direction «a» de la traction tectonique. En se basant sur les quartzites et les roches mylonitiques l'auteur postule un développement probablement contemporain des élements métamorphiques et structuraux le long du chevauchement Singuni pendant le mouvement tectonique et sur une grande échelle. Le quartzite de Gamri normal est plus métamorphosé à sa base le long des chevauchements Singuni et Uttarkashi tandis que l'intensité de la déformation s'accroÎt près du sommet du quartzite normal le long du Grand chevauchement Central. Ce fait montre le rÔle joué par les chevauchements dans la déformation cataclastique des roches et sa contribution au phénomène général du renversement du métamorphisme dans l'Himalaya inférieur.
    Notes: Zusammenfassung Im Gebiet von Garhwal (Lesser Himalaya) sind in einer NW-SE streichenden Zone entlang der Singuni-überschiebung in der metasedimentären Formation des Deoban-Tejam-Gürtels Mylonitgesteine ausgebildet. Petrographische Untersuchungen an verschiedenen Myloniten zeigen, da\ entlang der Singuni-überschiebung ein Quarz- und Feldspatporphyr eingedrungen ist. Dieser war zuerst in Almandin-Amphibolit-Fazies metamorphisiert, bevor durch eine tiefgreifende kataklastische und kristalloblastische Deformation sich Mylonitgestein in Grünschieferfazies entwickelte. SW-neigende Schieferung und eine Glimmerlineation, die in dieselbe Richtung abtaucht, sind in diesem Mylonit entwickelt. Der Quarzit ist auch in der Grünschieferfazies intensiv kataklastisch deformiert und stark geschiefert mit einem hervortretenden Glimmerband senkrecht zum Verlauf der Singuni-überschiebung, der Uttarkashi-überschiebung und der Gro\en Zentralüberschiebung in der „a“-Richtung des tektonischen Transportes. Anhand von Quarziten und Myloniten wird eine wahrscheinlich gleichzeitige Entwicklung der metamorphen und der tektonischen Elemente entlang der Singuni-überschiebung während gro\räumiger tektonischer Bewegungen postuliert. Normal aufgeschlossener Gamri-Quarzit ist nahe der Basis entlang der Singuni-überschiebung und der Uttarkashi-überschiebung stärker metamorphisiert, während die Intensität der Deformation nahe dem Top normal aufgeschlossener Quarzite entlang der Gro\en Zentralüberschiebung zunimmt. Dies spricht für die Rolle, die überschiebungen bei der kataklastischen Deformation von Gesteinen spielen, indem sie zu dem Phänomen verbreiteter Metamorphoseumkehr im Lesser Himalaya beitragen.

    Neutron-proton interaction and bandcrossing in the cranking model (1990)

    Notes: Abstract A cranked Hartree-Fock-Bogolubov formalism for a description of collective rotational states, which includes the n-p residual interaction along with pairing and is applicable to a neutron-proton system, is presented. A delta force form is used for the n-p residual interaction. A simple model is then developed where the valence neutrons and the valence protons occupy i13/2 and h11/2 orbitals, respectively. Results of these calculations are presented to show the effect of n-p interaction on the phenomenon of bandcrossing. Within the limits of such a restrictive model (which is particularly applicable to the (h11/2) p(i13/2) n bands in odd-odd nuclei) we find evidence for a shifting of the first bandcrossing frequency to a larger value. We find that n-p interaction may also affect many other phenomena in the high spin region.

    Notes: Summary The scattering of slow electrons by polyatomic molecules is studied within a full quantum formulation of the problem, and the wavefunctions of the target molecular bound electrons are obtained from a multicentre expansion (MCE) of Gaussian-type orbitals (GTOs) within the single-determinant Hartree-Fock (HF)-SCF scheme. It is shown that the scattering calculations require the solution of radial coupled equations where the interaction is obtained as a further multipolar expansion at the target centre of mass (c.o.m.), while the relevant numerical procedures are discussed for systems like SiH4, GeH4 and CF4. The ensuing interaction coefficients are used to carry out convergence studies of the scattering cross-sections, over a broad range of energies, in the case of silane targets. The results are found to be rapidly converging for such a system, while the different behaviour expected for other targets is also analysed and explained.
