Angular Distributions for theC13(d,n)N14Reaction

Abstract

Angular distributions of neutrons corresponding to transitions to the ground, first (2.31-MeV) and second (3.94-MeV) excited states have been measured at incident deuteron energies between 1.3 and 2.5 MeV. A single stilbene crystal spectrometer utilizing pulse-shape discrimination was employed to separate the ground and first excited states. The second excited-state neutron group was measured with a double crystal time-of-flight spectrometer using the associated gamma ray as a trigger. An analysis in terms of the plane-wave heavy-particle stripping theory was performed to describe the relatively high intensity of neutrons in the backward direction.
