Protons from the p+d Breakup Reaction at Proton Energies of 14 MeV and 10 MeV

Abstract

The energy spectra of the protons from the p + d breakup reaction as a function of angle were measured for the incident proton energies of 13.9 MeV and 10.1 MeV, using a particle selecting counter telescope consisting of a three- or five-layer proportional counter for the energy loss measurement and of an NaI scintillation counter for the energy measurement. Each of the observed energy spectra shows a rather steep rise at the maximum energy followed by a slight shoulder at large angles at the incident proton energy of 14 MeV, while the energy spectra at small angles do not show such shoulder. For both energies, each of the spectra has a maximum in its low energy side.
