Comment on a systematic distorted-wave Born-approximation prediction for two-nucleon transfer: Application to (d, α) experiments

In a recent study of ($d, \alpha$) reactions on medium and heavy nuclei, DelVecchio and Daehnick employ a well-matching condition which limits the choice of the optical model potentials. It is shown that in the authors' derivation of the well-matching condition, they violate the post-prior equality necessary for distorted-wave transition amplitudes.
