Abstract
A theoretical treatment of the combined effects of superconducting fluctuations and pair breaking on nuclear spin-lattice relaxation in small particles is described, in which the interaction of normal-state electrons with both fluctuations and impurities (i.e., renormalization of fermion propagators and impurity vertex corrections) is taken into account. The calculation is valid in the dirty limit and near the superconducting transition temperature, and exhibits qualitative agreement with presently available experimental results.
