Abstract

Angular distributions of single nucleon transfer reactions populating single particle states in the reactions138Ba(15C,14N)137Cs and138Ba(14C,13C)139Ba have been studied. The shapes of the angular distributions show differences for different final configurations. Using the reaction asymmetry it is possible to describe these differences consistently for all transitions by a spin-orbit potential. The polarisation of the outgoing fragments is discussed and its dependence on final configurations is explained. The spin-orbit potentials deduced from the reaction asymmetry are large, as compared to predictions of folding potentials. They are, however, consistent with measurements of spin-flip probabilities. The origin of the L-S interaction is to be found in coupling effects of second order in the heavy ion reaction.
