Abstract
We investigate the effects of taking the two-nucleon scattering matrices off energy shell in the first term of the nucleon-nucleus optical potential. In order to avoid Coulomb interference, only neutron-nucleus elastic scattering is considered. We look both for the possibility of improving the fit to the elastic nucleon-nucleus scattering observables by varying off-shell parametrization, as well as the possibility of extracting off-shell information on the nucleon-nucleon force.Keywords
