Superconducting fluctuation effects on the local electronic spin susceptibility. II. The impure case

For pt.I see ibid., vol.9, p.1699 (1977). The effect of impurity scattering on the leading divergence of the nuclear relaxation rate above a superconducting transition is investigated. It is found that impurity scattering smears the critical singularity into a peak. The peak is very sharp in the pure limit, when ( zeta /l)2 >1. The experimental implications are also briefly discussed.
