Abstract

Previous results of the present authors, who showed that observables of the hard-bremsstrahlung process pp → ppγ at beam energies ranging between 350 and 500 MeV are highly sensitive to the type of nucleon-nucleon potential (meson-exchange potentials versus the Moscow potential), are generalized by means of a relativistic analysis, which includes, above all, a modified current operator. As a result, the relevant cross sections decrease, while their angular dependence changes. However, the above high sensitivity to the type of potential survives and becomes quite significant even at the lowest beam energy of 280 MeV considered here, for which there are experimental data. They seem to favor one of the versions of the Moscow potential.
