    Electromagnetic probes of nuclear collisions at intermediate energy (1985)
    Springer
    The European physical journal 321 (1985), S. 589-592 
    Details
    ISSN: 1434-601X

    Topics: Physics
    Notes: Abstract We show that emission of high-energy electrons and photons in nuclear collisions at intermediate energies is sensitive to the space-time evolution of the reaction. The electron and photon spectra measure related but complementary quantities connected with the nuclear charge distribution. We show that at 60 MeV/u beam energy production of 50 MeV electrons is predicted to measurable probability.

    Systematics of spontaneous positron lines (1986)

    Topics: Physics
    Notes: Abstract Dynamical and spontaneous positron emission are investigated for heavy-ion collisions with long time delay using a semiclassical description. Numerical results and analytical expressions for the characteristic quantities of the resulting spontaneous positron line, i.e., its position, width, and cross section, are compared. The expected behaviour of the line position and cross section and its visibility against the spectrum of dynamically created positrons is discussed in dependence on the united chargeZ u of projectile and target nucleus in a range of systems fromZ u =180 up toZ u =188. The results are confronted with presently available experimental data, and possible implications on further experiments are worked out.

    Positron line structures in U-U collisions (1986)
    Springer
    The European physical journal 323 (1986), S. 275-280

    Keywords: 34.50.Fa ; 25.70.Gh ; 12.20.Fv

    Topics: Physics
    Notes: Abstract U-U collisions at energies near the Coulomb barrier are discussed. A quantum mechanical treatment of nuclear motion including the influence of quasibound states in a pocket of the scattering potential is developed. Positron emission probabilities are calculated exhibiting a sharp line due to the decay of a hole in the supercritical 1s-state. In addition conversion processes and multiple pockets in the potential creating sidebands in the spectrum are computed.

    Electronic excitations in heavy ion collisions with sequential fission (1988)
    Springer
    The European physical journal 329 (1988), S. 365-369

    ISSN: 1434-601X
    Keywords: 34.50.Fa ; 25.70.Lm

    Topics: Physics
    Notes: Abstract We calculateδ-electron and positron distributions resulting from heavy ion collisions under consideration of a sequential fission in the outgoing channel. The resulting spectra are found to be only weakly sensitive to the underlying dynamics of the fission process. Thus experiments of deep inelastic scattering provide information mainly on the primary reaction process.

    Description / Table of Contents: LiSmAlF6  -  the First Fluoroaluminate with Divalent SamariumLiSmAlF6, the first quaternary fluoride with Sm2+ that has been obtained as red transparent single crystals, is formed while heating corresponding mixtures of the starting materials in niobium or tantalum crucibles under argon after 7-10 d at about 800°C. Orange-red, microcrystalline powder samples of LiSmAlF6 could be prepared at T ≤ 700°C after 1-2 d under the same conditions.LiSmAlF6, crystallizes as a new structure type in P6322 (Nr. 182) with a = 507.9(1), c = 1 040.5(1) pm and Z = 2 (CAD4, 2 512 Io, Rw = 2,3%). The crystal structure of LiSmAlF6 is related to the LiCaAlF6 structure type whereby the essential difference lies in the coordination of the M2+ ions. Ca2+, as well as Sr2+ in LiSrAlF6, exhibit octahedral coordination, whereas Sm2+ has, surprisingly, trigonal prismatic coordination to F-. The two triangles of the SmF6 prism are twisted by 8.3° with respect to each other.Measurements of the magnetic susceptibility show the temperature dependence typically found for Sm2+. The Madelung part of the lattice energy has been calculated and is discussed.
    Notes: LiSmAlF6, das erste in Form roter, transparenter Einkristalle erhaltene quaternäre Fluorid mit Sm2+, bildet sich beim Erhitzen geeigneter Ausgangsmenge in Niob- oder Tantaltiegln unter Ar nach 7-10 d bei ca. 800°C. Orangerote, mikrokristalline Pulverproben von LiSmAlF6 können bei T ≤ 700°C bereits nach 1-2 Tagen unter sonst gleichen Bedingungen dargestellt werden.LiSmAlF6 kristallisiert in einem neuen Strukturtyp in P6322 (Nr. 182) mit a = 507,9(1), c = 1 040,5(1) pm und Z = 2(CAD4, 2 512 Io, Rw = 2,3%). Die Kristallstruktur von LiSmAlF6 ist dem LiCaAlF6-Typ verwandt, zeigt aber den wesentlichen Unterschied in der Umgebung für M2+ : Ca2+, wie auch Sr2+ in LiSrAlF6, werden oktaedrisch, Sm2+ jedoch überraschenderweise trigonal-prismatisch von F- koordiniert. Die beiden Dreiecke des SmF6-Prismas sind um 8,3° gegeneinander verdreht.Messungen der magnetischen Suszeptibilität zeigen die für Sm2+ typische Temperaturabhängigkeit. Der Madelunganteil der Gitterenergie wurde berechnet und diskutiert.
