Description

The JISP16 nucleon-nucleon potential [1] is applied to investigate the nucleon induced deuteron breakup reaction at energies E=13 and 65 MeV. We use the formalism of Faddeev equation [2] and proceed like in the case of the application of the JISP16 potential to the elastic scattering process [3].
Our study reveals that this force delivers, in general, qualitatively a similar description of the exclusive cross-section and analyzing power for the studied reaction to the one based on the standard realistic nucleon-nucleon AV18 interaction [4]. However, in some regions of the phase space, the differential cross sections based on the JISP16 and on the AV18 forces differ by more than 100% and 50% at E=13 and E=65 MeV, respectively. In the case of analyzing power – there is a difference of more than 100% at E=65 MeV. Such specific parts of the phase space can be used to fine-tune the JISP16 potential parameters.
