Fusion with exotic nuclei using a microscopic approach

Abstract

Fusion reactions near the barrier energy are studied in this proceedings with the Hartree-Fock (HF) method, on systems involving 40–54Ca+116,132Sn. Both static and time-dependent (TDHF) versions of the method are used to probe what structure effects play a role in the fusion barrier energy. In static HF calculations for fusion, ground state properties of the nuclei influence the barrier energy. When dynamics are added in with TDHF, some effects from static properties (for example, the neutron skin) disappear. To understand the role of vibrations in dynamic reactions, TDHF is used in conjunction with the coupled-channels approach. Discussion on the effects of transfer is also presented. Show more
