Study of Proton and Deuteron Spectra from Proton Induced Reactions at Intermediate Energies

Abstract

Intermediate-energy nucleon-nucleus interactions were investigated in order to achieve a more comprehensive understanding of spallation reaction and heavier fragments productions. Measurements of proton and deuteron production reactions for 300- and 392 MeV proton incidence were carried out at RCNP ring-cyclotron facility. Inclusive 12C(p, p′x) and 12C(p, dx) spectra at 300 MeV were measured in a wide energy range and compared with two theoretical calculations: the quantum molecular dynamics model and the intranuclear cascade model. The calculations of the INC model were in good agreement with the experimental results in the quasifree region. The deuteron production cross sections calculated by the QMD model were much smaller than the ones obtained by the measurement. The cause of this discrepancy was discussed in terms of a deuteron knockout process.
