Abstract
A complete potential model for nucleon-nucleon bremsstrahlung is used to test t matrices of recent NN potentials. ppγ and npγ cross sections and spin observables are calculated using the Paris, Bonn-B, and inversion potentials to the most recent phase shift analyses and Bonn-B phase shifts. We confront our results with older noncoplanar ppγ data from Harvard and most recent but inclusive data from Saclay and the Indiana University Cyclotron Facility. We obtain a good agreement between experiment and theory for all potentials. Nonlocality effects of potentials, supposedly discerned by bremsstrahlung, are small in comparison to data errors and differences between the potentials themselves.
