Abstract
The reaction has been studied over the proton energy range 0.1 to 6.2 Mev, by detecting the gamma rays with a sodium iodide scintillation counter. The 90° excitation function rises to a maximum in the region of 4 to 5 Mev and drops off slightly at higher energies. The angular distribution, measured at four energies, shows that in addition to the distribution previously reported there is a small asymmetry about 90° of the form , which increases with proton bombarding energy. This asymmetry has been studied over the entire energy range. Absolute yield measurements of the reaction give a 90° differential cross section at 1 Mev at 3.65× per steradian, which is considerably lower than has been previously reported.
