Cluster representation of 6Li and the finite-range distorted-wave Born approximation analysis of 6Li-induced alpha transfer reactions

With a view of examine the suitability of the various different forms of α-d cluster representation of 6Li used in the literature based on different criteria, for the α-transfer reaction analysis, finite range distorted-wave Born approximations calculations have been made in the present work for (6Li,d) reactions with various forms of cluster representation of 6Li and they are compared with the angular distribution data on the targets 26Mg, 27Al, 29Si, and 31P, at a bombarding energy of 36 MeV. It is found that (a) the single node wave function T/sub alphad/ introduced by Kubo and Hirata with corresponding Woods-Saxon form of V/sub alphad/ is not found to fit the angular distribution data at all, (b) the zero node Eckart function form of T/sub alphad/ with the corresponding V/sub alphad/ with attractive and repulsive part is also not successful, and (c) the zero node wave function generated by a Woods-Saxon form of potential with a hard repulsive core of R/sub core/ = 1.25 fm introduced by Watson et al. is also unsatisfactory. However, the Watson form modified by reducing the hard core radius to R/sub core/ = 0.6 fm predicts angular distributions satisfactorily. These results are not affected by the different choices of optical model parameters
