With the aid of neutron detectors having thresholds at 1, 5, and 12 Mev, the angular distributions and average cross sections of the C/sup 12/(He/sup 3/ ,n)O/sup 14/ reaction were investigated at 19-, 22-, and 25-Mev He/sup 3/ energy. All angular distributions show strong forward peaking suggestive of direct interactions. One case, involving only transitions to the ground state, exhibits a type of structure similar to that of protons from the C/sup 12/(He/sup 3/,p)N/ sup 14/ reaction to the first excited state, the T = 1 analog of the O/sup 14/ ground state. However, the momentum transfer at a reasonable radius is such that plane-wave theory would predict a minimum at 0 un. Concent 85% instead of the strong forward peak observed. (auth)
