Abstract: The attenuation coefficients are obtained for longitudinal waves in the limit ql≫1 for superconductors containing nonmagnetic Anderson impurities that give rise to local spin fluctuations (LSF). The multiplicative renormalization approach is used to treat the Coulomb repulsion between pairs of d electrons of opposite spins localized on an impurity site. Several thermodynamic properties of the LSF superconductors are obtained. The attenuation coefficient close to T cis obtained by renormalizing the propagator lines and vertices appearing in the leading diagrams in the expansion of the density-density correlation function. Comparison is made with the attenuation coefficient for a superconductor having nonmagnetic localized states formed about the transition metal impurities. © 1985 Plenum Publishing Corporation.
