• The two-step (p, d)(d, t) process in strong (p,t) transitions, <48> Ca(p, t)<46>Ca(0^+, g.s.; 2^+, 1.34 MeV) at 20 MeV and 40 MeV and <116>Sn(p, t)<114>Sn(o^+, g.s.) at 20 MeV are investigated in terms of "second order DWBA" with finite-range calculations of the non-orthogonality terms of the transition matrix element. In all the cases investigated, the contribution of the two-step process is as much as that of the one-step process. The cross sections of the Ca transitions are well accounted for by the one-step plus two-step mechanism. For the Sn transition, a strong enhancement of the two-step amplitude is found. It is as much and due to essentially the same mechanism as the well-known enhancement of the one-step amplitude caused by the pairing correlation in the BCS ground states of the Sn nuclei.
