Forward- and Backward-Angle Differential Cross Section for Neutron-Proton Capture at 72 MeV

Abstract

The neutron-proton capture differential cross section has been measured at extreme forward and backward angles for 72-MeV neutron energy corresponding to a $\ensuremath{\gamma}$-ray energy of 38.2 MeV in the inverse reaction. The results agree well with recent photodisintegration data at forward angles, but only partially with potential model calculations.
