Finite-Range Full-Recoil Calculation for Two-Nucleon Transfer between Heavy Ions

A distorted-wave Born-approximation (DWBA) calculation has been done for the reaction ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ni}$(${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$)${}_{}{}^{64}{}_{}{}^{}\mathrm{Ni}$, in which full account is taken of finite-range and recoil effects. It is found that finite-range no-recoil calculations for this reaction overestimate the DWBA cross-section by about a factor of 5. The no-recoil result concerning the strong dependence of the cross section on the single-particle states involved is confirmed by this fullrecoil calculation.
