Abstract

Abstract The prompt gamma-rays 1266-keV 31P p(1, 0) and 2234-keV 31P p(2, 0) induced by 5 MeV protons were measured during irradiation of 12 high purity phosphorus compounds. Stopping powers of target materials were calculated from tables and the use of the Bragg-Kleeman rule. Apparent discrepancies in the measured yields could point to deviations from the Bragg-Kleeman rule, and hence to molecular effects. The value of any molecular effects was found to be ≦ 7.9%.
