Entrance channel dependence of fusion-fission dynamics in mass ∼ 200 region

Quasi-fission process can easily be distinguished, at least conceptually, from the equilibrated fission process. The practical distinction, however, often hinges on the subtle differences in angular and mass distributions. While the mass distribution is nearly symmetric in both fission and quasi-fission processes the width of the mass distribution in quasi-fission is wider than that from the fission process signifying the non-equilibration in mass degree of freedom for the quasi-fission process. The angular distributions are also more strongly peaked along the beam axis in the quasi-fission reaction signifying its more direct nature
