Isospin symmetry breaking nucleon-nucleon potentials and nuclear structure

Nuclear Theory 2009-10-31 v1

Abstract

Modern nucleon-nucleon (NN) potentials, which accurately fit the nucleon-nucleon scattering phase shifts, contain terms which break isospin symmetry. The effects of these symmetry violating terms on the bulk properties of nuclear matter are investigated. The predictions of the charge symmetry breaking (CSB) terms are compared with the Nolen-Schiffer (NS) anomaly regarding the energies of neighboring mirror nuclei. We find that, for a quantitative explanation of the NS anomaly, it is crucial to include CSB in partial waves with L>0L>0 (besides 1S0^1S_0) as derived from a microscopic model for CSB of the NN interaction.
