A broad structure has been observed in (p, t) reactions on the tin isotopes /sup 112/Sn, /sup 116/Sn, /sup 118/Sn, /sup 120/Sn, /sup 122/Sn, and /sup 124/Sn between 7 and 9 MeV of excitation energy. The width of the peak has a minimum of around 1.9 MeV for the reaction /sup 116/Sn(p, t) and increases for both the /sup 112/Sn(p, t) reaction and for the heavier tin targets, but the excitation energy of the structure increases with mass number. The measured angular distributions of the bump in /sup 110/Sn, /sup 114/Sn, and /sup 120/Sn agree reasonably well with single-step, distorted-wave Born-approximation calculations. The widths of the peaks observed in two neutron transfer show the same trends with mass number as the widths of the single hole states observed in one neutron transfer reactions. It appears that the peak contains components which arise from the pickup of one particle from a deep orbit and one particle from a valence orbit, plus possibly some contribution from pickup of two particles from deep orbits.
