Query: Cooper pair transfer in nuclei   The second order DWBA implementation of two-particle transfer direct
reactions which includes simultaneous and successive transfer, properly
corrected by non-orthogonality effects is tested with the help of controlled
nuclear structure and reaction inputs against data spanning the whole mass
table, and showed to constitute a quantitative probe of nuclear pairing
correlations.
