Abstract
Motivated by recent discussions concerning the manner in which damping appears in the electric polarizability, we show that (a) there is a dependence of the nonresonant contribution on the damping and that (b) the damping enters according to the “opposite sign prescription.” We also discuss the related question of how the damping rates in the polarizability are related to energy-level decay rates.
