Role of Three-Nucleon Forces in Neutron-Rich Nuclei Beyond 132Sn

Nuclear Theory 2015-07-02 v1

Abstract

The role of three-nucleon forces (3NF) in the description of nuclear structure properties is nowadays a main topic in the field of microscopic many-nucleon calculations. We investigate the relative weight between effective two- and three-nucleon forces in neutron-rich nuclei beyond the doubly-closed 132Sn core within the realistic shell-model framework, studying the evolution of the spectroscopic properties of N=82 isotopes and heavy tin isotopes. This problem is tackled indirectly without explicitly taking into account effective 3NF through the comparison of the results of shell-model calculations obtained from realistic on-shell-equivalent low-momentum potentials.
