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

With a view to 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 approximation 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 ψ_αd introduced by Kubo and Hirata with the corresponding Woods-Saxon form of V_αd is not found to fit the angular distribution data at all, (b) the zero node Eckart function form of ψ_αd with the corresponding V_αd 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 R_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_core=0.6 fm predicts angular distributions satisfactorily. These results are not affected by the different choices of optical model parameters. NUCLEAR REACTIONS (⁶Li,d), FRDWBA calculations with different α-d cluster representations of ⁶Li.
