Nucleon-Nucleon Models, Charge Splitting, and the Nucleon-Nucleon Data near 210 MeV

Abstract

Phase-shift analyses have been made of the nucleon-nucleon scattering data near 210 MeV. Several nuclear potential models are compared with the results and are found to be clearly distinguishable by differences in their isospin-singlet phase shifts, particularly by the coupling parameter ${\epsilon }_1$ which is of importance for nuclear physics. There is no evidence of charge splitting in the ${}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}$ state.
