Neutron Emission in Strongly Damped Collisions ofKr86onEr166at 602 MeV

The neutron multiplicity was measured in coincidence with both binary products of the strongly damped collisions of ${}_{}{}^{86}{}_{}{}^{}\mathrm{Kr}$ on ${}_{}{}^{166}{}_{}{}^{}\mathrm{Kr}$ at 602-MeV beam energy. The measured ratio of the neutron multiplicities for the light and heavy fragments is in good agreement with the corresponding mass ratio for all mass divisions. The observed multiplicities as well as velocity and angular distributions of the neutrons are consistent with statistical-model calculations assuming isotropic evaporation of neutrons from fully accelerated, unpolarized fragments.
