Abstract

Superdeformed excitations in Po198 were studied using the Yb174(Si29,5n) reaction and γ-ray spectroscopy with Gammasphere. Energy-spin entry distributions for populating normal (ND) and superdeformed (SD) excitations were extracted by gating on discrete ND and SD transitions, respectively. Information on the SD excitation energy, SD well depth, and fission barrier in Po198 was deduced.
