Abstract

Angular distributions for the transitions to the ground and excited states of 12B from the 12C(7Li, 7Be)12B reaction at 82 MeV were measured. The data were analyzed in the framework of distorted wave born approximation for the direct charge-exchange and coupled reaction channels method for the two-step sequential nucleon transfers. It was shown that the two-step sequential nucleon transfer is the dominant mechanism in the investigated angular range and the direct mechanism becomes important only for small angles (θcm<10°).
