Diffusive Phenomena in the Charge and Angular Distributions for the ReactionAu197+ 620-MeVKr86

Abstract
The cross sections and the kinetic energy distributions of fragments with individually resolved atomic numbers have been measured as a function of angle. The variations in the Z distribution widths with angle and the change of the angular distributions from side peaked for Z's close to 36 to forward peaked for Z's far removed from 36 dramatically demonstrates the presence of diffusion of nucleons between the target and projectile.
