Shell effects in quasifission and implications for fission

ORAL

Abstract

Quasifission reactions have been of great interest in recent years particularly in connections with the formation of superheavy elements and a source for producing neutron rich nuclei. Such reactions proceed through regions of periodic table where the dynamical evolution of quantal shell effects influence the formation of final fragments. The time-dependent density functional theory (TDDFT) has been found to be an excellent theoretical tool to study these reactions microscopically [1-4]. In this talk we discuss the recent results for quasifission reactions obtained using the TDDFT. In, particular we focus on the observed shell effects in these calculations and their relevance and/or relationship for shell effects in fission dynamics.
