It is a common procedure in DWBA analyses to calculate radial form factors characteristic of single-nucleon states in a Woods-Saxon (WS)well of radius R = roA¢. A radius parameter r o ~ 1.25 fin, a diffuseness a = 0.65 fm and a spin-orbit term 2 = 25 are often used, while the potential depth is adjusted to reproduce the experimental values of binding energies, i.e. the nuclear separation energies. It has been indicated by Friedman et aL ~) that the geometrical parameters of the potential well are not uniquely determined and hence that the sub-Coulomb stripping 2) cross sections calculated with these form factors are not reliable. In particular, the calculated * Research supported in part by the US National Science Foundation. ,t Fellow of the Niels Stensen Foundation, the Netherlands.

N2 - The single-neutron pick-up reaction cross sections appear to be better correlated with the rms radius of the neutron orbit rather than with r0, the radius parameter of the single-particle Woods-Saxon well. Form factors which correspond to particles bound by the experimental separation energies and which have rms radii for the 2s 1 2, 1d 3 2 and 1f 7 2 orbits obtained from Coulomb energy shifts, lead to spectroscopic factors and S>/S< ratio for the 46,48,50Ti(p, d) reactions which are in a much better agreement with theoretical expectations than those obtained with constant r0.
