Note on a Nucleon-Nucleon Potential

A nucleon-nucleon potential was used in an approximate representation of the YLAM and YLAN3M phenomenological phase parameter fits to p-p and n-p scattering data. The potential employs a hard core and is different for singlet-even, singlet-odd, triplet-even, and triplet-odd states. It consists of central, tensor, spin orbit, and quadratic spin orbit parts. The latter are especially indicated by the singlet-even and also by the triplet-even interactions and are used only for even states. Coefficients in formulas for the potential are tabulated and the quality of agreement with experiment is discussed.
