The microscopic; aprroach to calculating single-nucleon transfer form factors is applied to reactions in the region near Ca, e.g. /sup 42/Ca(p,d)/sup 41/Ca and /sup 40/Ca(d,p)/sup 41/Ca. The interaction of the transferred nucleon with the /sup 40/Ca core is taken to be the single-particle Hartree- Fock potential of Tarbutton and Davies, based on a twobody potential developed by Nestor. Realistic effective interactions, including core-polarization renormalization, are used for the interaction of the transferred nucleon with valence nucleons and holes. The results are compared to form factors calculated with Woods-- Saxon core interactions and phenomenological residual interactions. It is found that the use of the Hartree-- Fock potential yields results which are significantly different from those obtained from Woods- Saxon wells of standard geometry (r/sub o/ = 1.25 fm, a = 0.65 fm). Form factors calculated with the Hartree- Fock potential tend to be larger in the surface and smaller in the interior, compared to those calculated with the Woods- Saxon. A Woods- Saxon well equivalent to Hartree- Fock gives almost identical results in some but not all cases, but the parameters of this well are quite different from the standard geometry and are highly state dependent. The form factors are found to be much less sensitive to the effective two-body interaction of the transferred nucleon with the valence particles and holes. (auth)
