Non-Perturbative Treatment of Excitation and Ionization in U sup 92+ +U sup 91+ Collisions at 1 GeV/Amu

摘要

Inner shell excitation and ionization processes in relativistic collisions of very heavy ions are treated by a non-perturbative method for the first time. The time-dependent Dirac equation is solved by a finite difference method for the scattering of U sup 92+ on U sup 91+ at Esub(lab) = 1 GeV/amu and zero impact parameter. The K-shell ionization probabilities are compared with those resulting from first-order perturbation theory. (ERA citation 11:035043)
