Abstract
A general theoretical expression for P+, the fraction of ionized parti cles sputtered from an electronically excited substrate is derived. Th e substrate excitation is described in terms of a time dependent T-mat rix at the Fermi energy. To illustrate the effect of substrate excitat ions more explicitly a simple formula for P+ is derived under the assu mption that the particle is sputtered at a very low velocity.
