Fission fragment mass-angle correlations and mass ratio distributions have been measured for the reactions O16+Os186, Mg24+Hf178, S34+Er168, and Ti48+Sm154, forming the Po202 composite nucleus, at near barrier energies. Systematic analysis based on the expected dependence of the variance of the mass distribution on the angular momentum and temperature of the compound nucleus indicate that the two lighter systems evolve through true compound nucleus fission. Evidence of quasifission was observed...[Show more]
