Attempt to Fix the Nucleon-Nucleon Parameters by Examining Nucleon-Nucleus Scattering

Abstract

The scattering of protons and neutrons from carbon at 142, 210, and 310 MeV is calculated using an optical potential obtained from nucleon-nucleon scattering amplitudes with the impulse, single-scattering, and energy-shell approximations. The integral scattering equation in momentum space is solved numerically using this potential. The present calculation is compared to previous approximate solutions and to the data. An attempt is made to choose among the currently available nucleon-nucleon phase-shift sets.
