Angular distributions of the tensor analyzing powers {ital A}{sub {ital yy}} and {ital A}{sub {ital zz}} have been measured for the ground-state transition in the {sup 93}Nb({ital {rvec d}},{sup 3}He){sup 92}Zr reaction at {ital E}{sub {ital d}}=12 MeV, and of {ital A}{sub {ital zz}} for the ground-state transitions in {sup 63}Cu({ital {rvec d}},{sup 3}He){sup 62}Ni at {ital E}{sub {ital d}}=8 MeV and {sup 89}Y({ital {rvec d}},{sup 3}He){sup 88}Sr at {ital E}{sub {ital d}}=10.5 MeV. The data are compared with predictions of full finite-range distorted-wave Born approximation (DWBA) calculations from which the asymptotic {ital D}- to {ital S}-state ratio, {eta}, for {sup 3}He is extracted to be {minus}0.0386{plus_minus}0.0045{plus_minus}0.0012. The difficulties with a choice of deuteron tensor optical potentials used in the DWBA calculations are discussed.
