Angular distributions of the reaction 12 C( 7 Li, t) 16 O have been measured at E lab = 15, 21.1 and 24 MeV with a magnetic spectrograph and a d E /d x — E telescope. From the shape of the angular distributions and the weak excitation of the 2 − state at E x = 8.87 MeV in 16 O it is concluded that the reaction proceeds dominantly by a direct α-transfer. Contributions from compound nucleus formation were estimated from a Hauser-Feshbach calculation. The angular distributions were analysed by means of the DWBA, which has been modified to take into account the relative p-state between the α-particle and the triton in 7 Li. Approximations valid for a surface reaction were used to simplify the theory. The calculations are able to reproduce the essential features of the angular distributions. Reduced α-widths were extracted for some states in 16 O. |
