Abstract

With a view to examine the suitability of the various different forms of αd cluster representation of Li6 used in the literature based on different criteria for the α-transfer reaction analysis, finite-range distorted-wave Born approximation calculations have been made in the present work for (Li6,d) reactions with various forms of cluster representation of Li6 and they are compared with the angular distribution data on the targets Mg26, Al27, Si29, and P31 at a bombarding energy of 36 MeV. It is found that (a) the single node wave function ψαd introduced by Kubo and Hirata with the corresponding Woods-Saxon form of Vαd is not found to fit the angular distribution data at all, (b) the zero node Eckart function form of ψαd with the corresponding Vαd with attractive and repulsive parts is also not successful, and (c) the zero node wave function generated by a Woods-Saxon form of a potential with a hard repulsive core of Rcore=1.25 fm introduced by Watson et al. is also unsatisfactory. However, the Watson form modified by reducing the hard core radius to Rcore=0.6 fm predicts angular distributions satisfactorily. These results are not affected by the different choices of optical model parameters.
