    Notes: Abstract Single crystalline specimens of RNi2B2C (R=Y, La) and Y(Ni.7Co.3)2B2C (non-superconducting reference) have been isolated from polycrystalline samples and successfully orientated. All four observable Raman peaks could be measured and unambiguously be attributed to vibrations of B and Ni atoms. Most important, we can show that a broadening of the B-A1g mode also occurs in non-superconducting reference samples and should therefore not be taken as an evidence for a dominant role of the B-A1g mode in the pairing interaction.

    Notes: Bei der Gefriertrocknung von Lösungen fadenförmiger und kugelförmiger Hochpolymerer, niedermolekularer Zucker und sogar anorganischer Salze wurden Gerüststrukturen von teilweise bemerkenswerter Festigkeit erhalten. Das makroskopische Bild der Trockensubstanzen wird bei allen Stoffgruppen durch die Textur des ausfrierenden Lösungsmittels bestimmt.

    A far-wing line shape theory which satisfies the detailed balance principle (1995)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: A far-wing theory in which the validity of the detailed balance principle is maintained in each step of the derivation is presented. The role of the total density matrix including the initial correlations is analyzed rigorously. By factoring out the rapidly varying terms in the complex-time development operator in the interaction representation, better approximate expressions can be obtained. As a result, the spectral density can be expressed in terms of the line-coupling functions in which two coupled lines are arranged symmetrically and whose frequency detunings are omega - 1/2(omega(sub ji) + omega (sub j'i'). Using the approximate values omega - omega(sub ji) results in expressions that do not satisfy the detailed balance principle. However, this principle remains satisfied for the symmetrized spectral density in which not only the coupled lines are arranged symmetrically, but also the initial and final states belonging to the same lines are arranged symmetrically as well.
