Measurements of the tensor analyzing powers have been obtained for (d-->,t) reactions on 91Zr, 118Sn, 119Sn, and 208Pb for deuteron energies both above and below the Coulomb barrier. The measurements are sensitive to the presence of D-state components in the triton wave function and allow the determination of a parameter D2. This parameter is a measure of the importance of triton wave function components in which one neutron moves with orbital angular momentum L=2 relative to the deuteron center of mass. Values of D2 are extracted from the tensor analyzing power measurements by making use of distorted-wave Born approximation calculations. Analysis of the sub-Coulomb measurements leads to D2=-0.279+/-0.012 fm2, which is somewhat larger in magnitude than recent theoretical predictions.
