Differential cross sections were measured as functions of angle and bombarding energy in the region from 1 to 2 Mev for the following reactions: (1) / sup 14/N(t,t)/sup 14/N; (2) /sup 14/N(t, alpha )/sup 13/C going to the ground state and the 3.09-Mev state in /sup 13/C; (3) /sup 14/N(t,d)/sup 15/N going to the ground state of /su p 15/N; and (4) /sup 14/N(t,p)/sup 16/N going to the ground state and the 0.120-, 0.295-, and 0.392-Mev states of /sup 16/N. The total cross sections for the last three of these reactions at 2 Mev are: (2) 11 and 6 mb; (3)48 mb; and (4) 7, 1, 9, and 8 mb, respectively. The energy and angular behavior of the differential cross sections suggest that most of these reactions proceed predominantly by direct interactions. The large absolute value of the cross section for the /sup 14/N(t,d/sub 0/)/sup 15/N reaction, as well as the energy and angular behavior of the differential cross section, suggest that this reaction may proceed by a cluster exchange process. Distorted-wave Born approximation calculations provide satisfactory fits to the (t, alpha /sub 0/) angular distribution, but not the (t,d/sub 0/). Planewave calculations including exchange stripping give more acceptable fits to the (t,d/sub 0/) data. (auth)
