FINAL AND PRIMARY YIELDS AND DISPERSIONS FOR STRONGLY DAMPED REACTION OF KR-86 + SN-124

Fragment mass numbers, charges, and kinetic energies were measured by time of flight and E techniques for reactions of Sn124 targets with Kr86 projectiles at laboratory bombarding energies of 440 and 720 MeV. Dispersions in kinetic energy and mass for fixed atomic number fragments are reported for strongly damped fragments; estimates of the primary dispersions in fragment excitation, kinetic energy, and mass are presented by using the statistical model to estimate broadening due to particle emission. The standard deviation in Q value is found to be nearly a constant 13% of the Q value at both bombarding energies. The experimental yield distribution are shown to be consistent with a division of excitation which is proportional to mass.
