摘要：

The statistical model of electrons in a small metallic particle is applied to calculate three expressions for the size dependent ac conductivity. The first expression is very simple. It is obtained with a sum-rule conserving ansatz for the electric dipole matrix element. The two other forms follow from generalizations of a quasiclassical approximation for the matrix element due to Gor'kov and Eliashberg. The results are discussed and related to other work. © 1990 Springer-Verlag.
