Charge Dependency of Strong Nuclear Force via Phase Shift Analysis of Nucleon-Nucleon Potential

Using the most recent phase shift data for pp, nn,and np elastic scattering for different states (l=0,1,…) in the energy rangeof 1 MeV to 350 MeV, the charge dependency of the strong nuclear forceis investigated. Our results indicate that although the chargeindependency holds in most of the energy range, such chargeindependency is broken in the particular energy range of 120 MeV to 200 MeV for all partial wave states considered here.
