Angular distributions for the N14(d, p)N15 reaction were investigated at nine deuteron energies ranging from 1.5 to 3.2 MeV. Measurements were carried out in the angular range from 0 to 165 degrees at intervals of 15 degrees. The results for the N14(d, p)N15 ground state reaction showed generally a forward peak, as was expected from deuteron stripping, and a considerable rise in backward directions. These experimental data were analyzed with the heavy particle stripping theory and parameters adjusted to get a best fit were obtained. With the exception at forward directions, the main feature of angular distributions was found to be very similar to that for the N14(d, n)O15 ground state reaction, which is the mirror reaction, at the same deuteron energies. At forward directions proton yields from the N14(d, p)N15 reaction were substantially larger than neutron yields from the N14(d, n)O15 reaction. Angular distributions for the first excited doublet state reaction were found to be nearly isotropic, but a slight peak was observed at about 60 degrees similarly at all deuteron energies. Total cross sections for both state reactions were also estimated. Excitation functions for the N14(d, p)N15 and N14(d, n)O15 ground state reactions showed similar behavior, having some resonance-like structures.
