Nucleon-nucleon t-matrix interaction for scattering at intermediate energies.

A local nucleon-nucleon effective interaction based on current phenomenological nucleon-nucleon scattering amplitudes has been constructed at several bombarding energies between 50 and 1000 MeV/nucleon within a dynamically nonrelativistic framework. The form of the interaction has been chosen for convenience in performing nucleon-nucleus scattering calculations in this energy range and for ease of comparison with one-boson-exchange potential models. Some properties of this interaction are compared with those of an earlier version based on an older set of nucleon-nucleon amplitudes.
