Angular Distribution of Gamma Rays from the ReactionC12(Li6,d)O16

Angular distributions of the 6.92- and 7.12-MeV $\gamma$ radiation from the reaction ${\mathrm{C}}^{12}({\mathrm{Li}}^6,d){\mathrm{O}}^{16}$ were measured as functions of bombarding energy in order to obtain information about the reaction mechanism. Bombarding energies were at, and below, the Coulomb barrier for these low, negative-$Q$ reactions. The tendency to proceed by a direct-reaction mechanism should be enhanced under these conditions. Results are compared with plane-wave calculations and are in reasonable agreement for the 6.92-MeV radiation but in strong disagreement for the 7.12-MeV radiation.
