Online published on 19 March, 2024. Abstract This brief communication presents the neutron-proton scattering phase shifts (SPS) and compares them with the outcomes obtained through the high-precision Argonne Av-18 potential. The results for S and D states are found to be in good agreement, while a slight shift in SPS is observed for the P state. However, these variations are found to be in good match again. The Morse potential has been identified as an ideal reference potential and has been chosen to model the interaction. The Morse 1S0 potential is compared with the precision Bonn, Reid, and Av-18 potentials, and variations in P-state potentials have been compared to those of Arndt.
