Mass, velocity, angular and charge-state distributions from the fusion ofS32andSn112

Abstract
Evaporation residues from the fusion of S32 and Sn112 at ES32=160 MeV were studied using an energy-mass spectrometer. The velocity selector of the energy-mass spectrometer was first utilized to measure summed fusion products as a function of velocity setting and reaction angle. In-flight mass separation of the fusion products with the energy-mass spectrometer identified masses 141, 140, and 139 from the evaporation of three to five nucleons from the Dy144 compound nucleus. Absolute cross-section measurements are compared to theoretical predictions of the statistical evaporation model. Velocity, angular and charge state distributions of evaporation residues are also compared to calculated values.
