NUCLEON-NUCLEON POTENTIALS AND THEIR TEST WITH BREMSSTRAHLUNG

A complete potential model for nucleon-nucleon bremsstrahlung is used to test t matrices of recent NN potentials. ppgamma and npgamma cross sections and spin observables are calculated using the Paris, Bonn-B, and inversion potentials to the most recent phase shift analyses and B onn-B phase shifts. We confront our results with older noncoplanar ppg amma data from Harvard and most recent but inclusive data from Saclay and the Indiana University Cyclotron Facility. We obtain a good agreem ent between experiment and theory for all potentials. Nonlocality effe cts of potentials, supposedly discerned by bremsstrahlung, are small i n comparison to data errors and differences between the potentials the mselves.
