The asymptotic [ital D]-state to [ital S]-state ratio of the [sup 3]H[r arrow][ital n]+[ital d] cluster wave function ([eta][sub [ital t]]) has been determined from measurements of sub-Coulomb ([ital [rvec d]],[ital t]) tensor analyzing powers. New measurements of the tensor analyzing power [ital T][sub 20] for ([ital [rvec d]],[ital t]) reactions on [sup 208]Pb and [sup 119]Sn at several different energies are presented. These data, along with previous measurements of [ital T][sub 20] and [ital T][sub 21] for several additional reactions and energies, are used in a distorted-wave Born approximation analysis that includes nuclear tensor potentials as well as long-range tensor potentials that arise from Coulomb interactions. A weighted mean of all fourteen statistically independent values gives the result [eta][sub [ital t]]=[minus]0.0431[plus minus]0.0025, where the quoted uncertainty includes statistical and systematic contributions. This result is compared with previous measurements and with predictions obtained from Faddeev calculations.
