An energy independent nucleon-nucleon potential model is described. The model represents the two-nucleon data below 315 MeV more faithfully than any other potential model known to date. The data include the effective range expansion parameters and the deuteron properties as well as the scattering data at higher energies. It is of special significance that the n-p data have been represented by the energy independent potential model in a satisfactory manner for the first time. For this purpose a quadratic LS potential was found essential in the T = 0 state. The T = 1 potential differs little from those previously proposed by several authors. The phase shifts predicted by the model are in fair agreement with the solutions YLAM (T = 1) and YLAN3M (T = 0) recently found by the Yale group.
