    Description / Table of Contents: Каменные ледники (глетчеры) широко распространены во многих горных системах мира. Они формируются в условиях вечной мерзлоты и глубокого расчленения рельефа. До сих пор эти перигляциальные формы рельефа остаются крайyе слабо изученными во всех отношениях, но особенно это касается их внутреннего строения, генезиса и эволюции. В отечественной литературе им уделяется мало внимания, хотя они встречаются в некоторых горных районах чаще, чем ледники. В занимательной форме описана история изучения, распространение, внешний облик, внутреннее строение, характер движения, генезис и эволюция каменных глетчеров. Рассмотрено их влияние на различные природные процессы в горах, высказаны соображения относительно взаимосвязи каменных глетчеров с хозяйственной деятельностью человека. Книга предназначена для широкого круга читателей, включая студентов и школьников.
    Description / Table of Contents: Stone glaciers (glaciers) are widespread in many mountain systems of the world. They are formed in conditions of permafrost and deep dissection of the relief. Until now, these periglacial landforms remain extremely poorly studied in all respects, but this is especially true of their internal structure, genesis and evolution. Little attention is paid to them in Russian literature, although they are found in some mountainous regions more often than glaciers. The history of study, distribution, external appearance, internal structure, nature of movement, genesis and evolution of stone glaciers are described in an entertaining form. Their influence on various natural processes in the mountains is considered, considerations are made regarding the relationship of stone glaciers with human economic activity. The book is intended for a wide range of readers, including students and schoolchildren.

    Retardation of dislocations by the Cherenkov mechanism in crystals with a soft mode (1988)
    Springer

    Notes: Abstract The retardation mechanism of dislocations in crystals with a soft mode on account of Cherenkov emission of soft optical phonons is considered in the present work. The conditions in which this retardation mechanism appears are examined for various orientations of the wave vector qc characterizing structural phase transition. It is shown that the threshold velocity of the retardation mechanism in the case where qc¦V (V is the velocity of motion of the dislocations) decreases on approaching the phase-transition temperature Tc in proportion to ¦tc−Tc¦. The dependence of the dynamic retardation coefficient B on the velocity V and the closeness to the point of structural phase transition is obtained.

    Description / Table of Contents: Zusammenfassung Die Wärmekapazitäten von NdCl2, SmCl2, EuCl2, DyCl2, TmCl2, DyCl3, YbCl3 und LuCl3 wurden im Temperaturbereich 10–320 K mit einem adiabatischen Mikrokalorimeter gemessen. Aus den Ergebnissen wurden die thermodynamischen Standardwerte berechnet. Die Wärmekapazität dieser Chloride setzt sich zusammen aus der Gitter-Wärmekapazität und einem Beitrag, infolge der thermischen Besetzung der niedrig-liegenden Stark-Niveaus (Schottky-Anomalie). Die Schottky-Wärmekapazität wurde als Differenz zwischen experimentellenC p -Werten isostruktureller para- und diamagnetischer Chloride geschätzt. Die experimentell gefundenen Schottky-Beiträge stimmen gut überein mit den Werten, die für SmCl2, TmCl2 und YbCl3 nach einem verallgemeinerten Modell der Stark-Aufspaltung der Hauptterme der betreffenden Ionen im orthorhombischen bzw. monoklinen Kristallfeld berechnet wurden.

Из полученных данных вычислены стандартн ые термодинамически е свойства. Теплоемкости хлорид ов состоят из решеточной теплоемк ости и дополнительно го вклада, вносимого термическ ой плотностью низколежащих электр онных уровней Штарка (аномалия Шоттки). Теплоемкость по Шоттки была определена как р азличие между экспериментальными значениями С для изос труктурных парамагнитных и диам агнитных хлоридов. Экспериментальные в еличины вкладов по Шо ттки для SmCl2, TmCl2 и YbCl3 хорошо согл асуются с вычисленны ми с помощью общей модели основного терма штар ковского расщеплени я соответствующих ион ов в кристаллическом поле орторомбической и мо ноклинной решеток.
    Notes: Abstract The heat capacities of the lanthanide chlorides NdCl2, SmCl2, EuCl2, DyCl2, TmCl2, YbCl2, DyCl3, YbCl3 and LuCl3 were measured at 10–320 K with an adiabatic microcalorimeter. Standard thermodynamic properties were calculated from the experimental results. The heat capacities of these chlorides are composed of the lattice heat capacity and an additional contribution caused by the thermal population of the low-lying Stark electronic levels (Schottky anomaly). The Schottky heat capacity was estimated as the difference between the experimentalC p values for the isostructural paramagnetic and diamagnetic chlorides. Experimental Schottky contributions were found to be in good agreement with those calculated for SmCl2, TmCl2 and YbCl3 via a general model of the main-term Stark splitting of the respective ions in the orthorhombic and monoclinic crystal fields.

    Prompt neutrino production in 400 GeV proton-copper interactions (1988)
    Springer
    The European physical journal 40 (1988), S. 497-522 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A new beam-dump experiment has been performed at the CERN Super Proton Synchrotron using the CHARM neutrino detector. The instrumentation and the statistics have been significantly improved with respect to earlier experiments. For a neutrino energy above 20 GeV the asymmetry of the prompt muon-neutrino and electron-neutrino fluxes $$[(v_\mu + \bar v_\mu ) - (v_e + \bar v_e )]/[(v_\mu + \bar v_\mu ) + (v_e + \bar v_e )]$$ is found to be 0.20±0.10 (stat.)±0.05 (syst.), and the asymmetry of prompt antineutrino and neutrino fluxes for muonneutrinos $$(v_\mu - \bar v_\mu )/(v_\mu + \bar v_\mu )$$ is 0.02±0.16 (stat.)±0.02 (syst.) in agreement with our previous results. For the cross-section times branching ratio for charm production and semileptonic decay we obtain a value of $$\sigma \times BR\left[ {D(\bar D) \to v_e (\bar v_e ) X} \right] = 1.9 \pm 0.2 \pm 0.2\mu b$$ per nucleon. We find no evidence forv τ orv x interactions. The $$(v_\tau + \bar v_\tau )$$ flux is less than 21% of the total prompt neutrino flux. We derive an improved limit on the branching ratio $$\pi ^0 \to v\bar v$$ of 6.5×10−6, and as a verification of the universality of the neutral weak coupling we find $$g_{v_e \bar v_e } /g_{v_\mu \bar v_\mu } = 1.05_{ - 0.18}^{ + 0.15} $$ .

    Total cross sections of charged-current neutrino and antineutrino interactions on isoscalar nuclei (1988)

    Topics: Physics
    Notes: Abstract New measurements of the total crosssections of charged-current interactions of muonneutrinos and antineutrinos on isoscalar nuclei have been performed. Data were recorded in an exposure of the CHARM detector in an 160 GeV narrow-band beam. The antineutrino flux was determined from the measurements of the pion and kaon flux, and independently from the muon flux measured in the shield; the two methods are found to agree. The neutrino flux was determined from the muon flux ratio forv μ and $$\bar v_\mu $$ runs which was normalized to the antineutrino flux. The cross-section slopes thus determined are $$\begin{gathered} \sigma _T^{\bar v} /E = (0.335 \pm 0.004(stat) \hfill \\ \pm 0.010(syst)).10^{ - 38} cm^2 /(GeV \cdot nucleon) \hfill \\ \sigma _T^v /E = (0.686 \pm 0.002(stat) \hfill \\ \pm 0.020(syst)).10^{ - 38} cm^2 /(GeV \cdot nucleon) \hfill \\ \end{gathered} $$ The momentum sum of the quarks in the nucleon and the ratio of sea quark to total quark momentum are derived from the measurements.
