Further Neutron-Proton Bremsstrahlung Results

Neutron-proton bremsstrahlung calculations predict cross sections integrated over the photon angle, ${\theta }_{\gamma }$, which show rather modest model dependence. However, the predicted photon angular distributions manifest a large model dependence. Unpublished data from a previous experiment were integrated over positive and negative photon angles and the ratio compared with model predictions. The results are that the potential model calculations of Brown and Franklin are favored.
