We have developed a hybrid method to treat charged‐particle impact ionization of complex atoms and ions. The essential idea is to describe the interaction between a fast projectile and the target perturbatively, up to second order, while the initial bound state and the ejected‐electron—residual‐ion interaction can be handled via a convergent R‐matrix with pseudo‐states (close‐coupling) expansion. Example results for ionization of the heavy noble gases (Ne—Xe) by positron and electron impact are presented. The general scheme for a distorted‐wave treatment of ionization by heavy‐particle impact is described.
