The S- and D-state radial components u/sub 0/ and u/sub 2/ of the relative motion between the clusters d + n in /sup 3/H, necessary in a full finite range distorted-wave Born-approximation analysis of (d,t) reactions, are calculated using realistic triton and deuteron wave functions derived from the Reid soft-core potential. The parameter D/sub 2/ which provides a measure of the asymptotic D state to S state ratio is found to be almost entirely determined by the triton D state, the deuteron D-state contribution being about 10%. Using the Strayer and Sauer triton wave function, the value D/sub 2/ = - 0.17 fm/sup 2/ is obtained after correcting the asymptotic behavior of the d-t overlap. This result suggests that the Reid soft-core potential overestimates D/sub 2/ by about 20% compared with values extracted from a local energy approximation analysis of (d,t) tensor analyzing power data. The difference between D/sub 2/ for (d,t) and (d,/sup 3/He) is discussed.
