Coulomb Energies and the Excess Neutron Distribution from the Study of Isobaric Analog Resonances

Abstract

The effects determining the energies of isobaric analog resonances are studied. In particular, the compound and continuum shifts, nuclear two-body correlations, isospin-nonconserving nuclear forces, and isospin impurity are discussed. These effects are important in deriving the excess neutron density from analog-resonance experiments.
