Nucleon Exchange andAZEquilibration in Interactions of 8.3-MeV/amuFe56Ions withFe56,Ho165, andBi209

Abstract
Yields have been measured with discrete Z and A resolution for Fe-like fragments produced in damped collisions between 8.3 MeV/amu Fe56 ions and Fe56, Ho165, and Bi209 targets. Both the fragment AZ ratio and the relationship between the variances of the mass and charge distributions are found to depend upon the degree of energy damping. These observations are consistent with similar time scales for evolution of the nucleon-exchange process, AZ equilibration, and energy dissipation.
