The neutron-transfer reaction, N/sup 14/(N/sup 14/,N/sup 13/)N/sup 15/ s, was investigsted from 6 to 60 deg c.m. with 28-Mev N/sup 14/ ions accelersted in the Oak Ridge 63-in. cyclotron. Circular strips of aluminuzn foil, each encompassing a known angular increment, were used to stop the radioactive N/sup 13/. Excited states in N/sup 13/ are unstable with respect to proton emission; the first excited state in N/sup 15/ was 5.28 Mev above ground. Therefore, N/sup 15/ nuclei resulting from transfers to the ground state of N/sup 13/ are at least 5 Mev more energetic than those resulting from transfers to N/sup 15/ excited states. The two groups of N/sup 13/ particles were distinguished by placing suitable absorbers in front of the aluminum catcher foils. It was found thst transfers to excited states bocome more abundant relative to ground state transfers as the incident N/sup 14/ energy is lowered. (auth)
