- Abstract
An analysis of neutron and proton scattering off Ca has been carried out. Real and imaginary potentials have been generated using the Nuclear Structure Method (NSM) for scattering with the Gogny D1S nucleon-nucleon effective interaction. Observables are well described by NSM for neutron and proton elastic scattering off Ca and for neutron scattering off Ca . For proton scattering off Ca, NSM yields a lack of absorption. This discrepancy is attributed to two-fold charge exchange ( p, n, p) contribution and coupling to Gamow-Teller mode which are not included in the present version of NSM. A recipe based on a Perey-Buck fit of the NSM imaginary potential and Lane model is proposed to overcome this issue in an approximate way.
