Blann, M; Remington, B A

We test a relaxation model based on two body nucleon-nucleon scattering processes to interpret phenomena observed in heavy ion reactions. We use the Boltzmann master equation to accomplish this. By assuming that the projectile nucleons share the total excitation with equal a-priori probability of all configurations, we are able to reproduce several sets of neutron spectra from /sup 20/Ne and /sup 12/C induced reactions on /sup 165/Ho. With no additional free parameters our model successfully reproduces subthreshold pion production cross sections, high energy ..gamma..-ray spectra, and angular distributions of high energy ..gamma..-rays. 40 refs., 12 figs., 2 tabs.
