Dynamics Of Matter-, Antimatter-atom Collisions

Abstract

Dynamical effects which lead to differences in the cross section for single- or multi-electron removal from atoms by singly-charged particle, (e, ē, p, P̄) impact are caused by the differences in mass and sign of the charge of the projectile. This fact, often masked by simple first order theories, has now been demonstrated both experimentally and by more appropriate and sophisticated theoretical methods. Here we summarize our recent work elucidating these effects using the classical trajectory Monte Carlo technique to examine the total cross sections, and various cross sections differential in angle and energy, for electron removal. These cross sections have been calculated for intermediate velocity (1 to 6 a.u.) collisions of e, ē, p and p̄ with H and He, and have been compared with other theoretical results and experimental measurements. © 1989.
