Abstract

The C12(d; p, n) reaction has been studied using the Rice University high resolution 180° magnetic spectrometer for deuteron energies of 4.66, 4.90 and 5.46 MeV. No evidence was found for the existence of a density of states cusp near the neutron threshold similar to that seen in the Be9(p; p′, n)Be8 reaction studied by Spencer et al.1). However, broad proton groups were observed at energies which correspond to the two-body sequential decay C12+dN14∗N13∗ +nC12+n+p. Two excited states in N13 involved in this were the known 3.51 and 3.56 MeV states. The proton groups show broadening and energy shifting due to the motion of the intermediate N13 nucleus. Theoretical line shapes have been calculated to compare with these data. The groups occur at proton energies of approximately 1.01, 1.04 and 1.08 MeV, with each broad group possesing a doublet structure with approximate widths at half height of 60, 50 and 90 keV corresponding to the deuteron bombarding energies of 4.66, 4.90 and 5.46 MeV respectively. No evidence for states at 5.51 and 6.10 MeV in C13 was observed.
