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.
