Abstract

The prompt gamma-rays of 2228 and 2230 keV from the reaction32S/p,p′γ/32S at Ep=5.0 MeV were measured during proton irradiation of 23 pure sulphur compounds of known composition. Elemental stopping powers were calculated from tables and used to compute the stopping power of the target material by Bragg's Law. Apparent discrepancies in the measured yield could point to deviations from Bragg's Law and hence to molecular effects. The value for any molecular effects was found to be ≦7.06%.
