Alpha-deuteron vertex constant of $sup 6$Li

The alpha-deuteron structure of the ground state of $sup 6$Li has been studied theoretically through phenomenological, resonating-group structure, shell model, and pole approximation methods. The asymptotic normalization constant of the $alpha$-d intercluster wave function is directly related to the $sup 6$Li:- $alpha$-d vertex constant C. Tabulated values of C$sup 2$ are given and possible sources of errors are discussed. 22 references (BJG)
