Effects of Strong Interaction on the Electromagnetic Dissociation

Abstract

We investigate effects of strong interactions on the electromagnetic dissociation of nuclei in heavy ion collisions. We start from the eikonal approach to the equivalent photon method to describe the electromagnetic contributions to the cross section of peripheral collisions. We summarize some results of this approach and characterize recent experiments in "universal plots". In the second part of this work, we give a straight forward method to include transitions induced by the strong interactions between the ions. We introduce different methods to obtain the nuclear transition potential, and study the behavior of the resulting nuclear contributions.
