Angular distributions for the reaction 124Sn(d, p)125Sn leading to the unresolved ground and O· 026 MeV levels and to the 0'210, O· 936, 1 -257, 1· 362, and 1 . 540 MeV levels of 125Sn have been measured with deuteron energies of 5· 1 and 12-0MeV. Spectroscopic factors have been extracted using the DWBA theory. The dependence of the calculations on various assumptions of the theory has been studied by comparing the results at both energies. The sub-Coulomb data have been found to yield more reliable spectroscopic factors because of the lack of sensitivity to the optical model parameters used in the distorting potentials.
