Influence of the short range nonlocal nucleon-nucleon interaction on the elastic n-d scattering:: Below 30 MeV -: art. no. 054001

A previously defined short range nonlocal nucleon-nucleon (NN) interaction, which more closely matches common expectations and reproduces the H-3 and He-3 binding energies, is tested in elastic scattering. Nonlocal P-wave interactions with modified on-shell behavior were constructed in order to produce better low-energy n-d analyzing powers. At low energies some of the changes are due to the correct 3N binding energy, however, there are effects due to the characteristic properties of the nonlocal interactions. There is an indication that p-d calculations based on the present nonlocal NN interactions (with or without the modified P-wave interactions) would produce the same quality or better agreement with the low- and medium-energy experimental data than the corresponding local NN interaction plus 3N force model.
