Proton loss by nuclear inelastic interactions in germanium

Abstract

The probability of protons undergoing nuclear inelastic interactions while stopping in germanium has been measured in a direct counting experiment using protons with energies between 25 and 49 MeV incident on a germanium detector. These values have been determined to an accuracy of approximately ±2%. Calculations of the proton reaction probability over the incident energy range 20–150 MeV have also been made, using previously reported proton total reaction cross sections. The experimental and calculated results agree to within ±1.8%.
