Two Distinct Quasifission Modes in the 32 S + 232 Th Reaction

du Rietz, Rickard; Dasgupta, Mahananda; Thomas, Renju; Gasques , Leandro; Hinde, David

Description

Comprehensive fission measurements, including mass-angle distributions, for the reaction of S32 with the prolate deformed nucleus Th232 at near-barrier energies show two distinct components in both mass and angle; surprisingly, both have characteristics of quasifission. Their relative probabilities vary rapidly with the ratio of the beam energy to the capture barrier, suggesting a relationship with deformation aligned (sub-barrier), or antialigned (above-barrier), configurations at contact.
