    On the decay of148Pm (1970)
    Springer
    The European physical journal 233 (1970), S. 391-397

    Topics: Physics
    Notes: Abstract TheΒ-γ directional correlation between the 1,930 keVΒ-group and the 511 keV cascadeγ-ray in the 5.4 d148Pm decay has been measured at 14 differentγ-energy points. The anisotropy is found to be positive and is (4.4±0.4)% at 1,210 keV. The energies of theγ-rays depopulating the levels in148Sm have been measured using a Ge(Li) spectrometer with an accuracy of better than 1 keV. Theγ-ray intensities have been determined within 15%.

    On the Peierls transition in the presence of disorder (1989)
    Springer
    The European physical journal 76 (1989), S. 33-41

    Notes: Abstract We consider the continuum approximation of a half-filled site-disordered Fröhlich chain in the mean-field approximation. We perform the configurational average over Gaussian-distributed and short-range-correlated potentials by means of the supersymmetry method and obtain an exact analytic formula for the integrated density of states containing many previously known special cases. It enables the minimization of the ground state energy with respect to the Peierls order parameter which is calculated in dependence on two disorder parameters describing forward and umklapp scattering. The Peierls transition proves to be continuous and takes place even if the density of states diverges at the Fermi energy, which eventually happens if only umklapp scattering is present.
