Pauli energy contribution to nucleus-nucleus interaction potentials

ORAL

Abstract

In this work we use the nucleon localization function (NLF) approach [1] to demonstrate the contribution of Pauli energy to nucleus-nucleus interaction potentials. This is a follow up on our previous work on assessing the Pauli effect on the formation of potential pockets in ion-ion interaction potentials [2]. Calculations are done using the density-constrained frozen density approach (DCFHF), the dynamical time-dependent density-constrained Hartree-Fock (DC-TDHF) method, as well as the full time-dependent Hartree-Fock (TDHF) method. We also utilize the Pauli localization function (PLF) to better visualize these effects. [1] T. Li, M. Z. Chen, C. L. Zhang, W. Nazarewicz, and M.
