Triton- and helion-induced cluster pick-up reactions on ^12,13C

Differential cross sections have been measured for the reactions (t,⁶He), (t,⁶Li), (t,⁷Li), (t,⁹Be) on ^12,13C; (t,⁸Li) on ¹³C; for (³He, ⁶Li) on ^12,13C and (³He, ⁷Be) on ¹²C over the range 10 degrees -100 degrees CM. For the (³He, ⁷Be) and (³He, ⁶Li) reactions on ¹²C, analysing powers were measured over the range 20 degrees -75 degrees CM. Finite-range DWBA analyses have examined the effects of different optical potentials, including spin-orbit potentials, and bound-state potential geometries. Microscopic descriptions of the alpha -projectile cluster wavefunction and a number of potential descriptions have been used to generate form factors for the alpha -pick-up reactions. Spectroscopic factors have been extracted for all the reactions and compared with shell-model calculations.
