Spectroscopic Factors from (d,p) Reactions

The spectroscopic factor dependence of the revised model of Butler et al. for deuteron stripping is examined. It is shown that the factor ${\mathrm{}(1-S)\mathrm{}}^{-2\mathrm{}}$ multiplying the cross section in this model results from an incorrect evaluation of a matrix element. The correct evaluation reduces the revised-model matrix element to the original Tanifuji-Butler result.
