Abstract
In case of thep-α system, the Coulomb exchange potential of the resonating group model and of the fish bone optical model are compared with each other. It is seen that the difference between the two approximations arises mainly from the unrealistic shortdistance behaviour of the proton-protone 2/r potential, which has been assumed in both models. In case of the α-16O system, it is demonstrated that the importance of the Coulomb exchange potential can be very much reduced by an off-shell transformation.
