Angular distributions for the N 14 ( d , p )N 15 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 N 14 ( d , p )N 15 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 N 14 ( d , n )O 15 ground state reaction, which is the mirror reaction, at the same deuteron energies. At forward directions proton yields from the N 14 ( d , p )N 15 reaction were substantially larger than neutron yields from the N 14 ( d , n )O 15 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 section for both state reaction were also estimated. Excitation function for the N 14 ( d , p )N 15 and N 14 ( d , n )O 15 ground state reaction showed similar behavior, having some resonance-like structures.
