Study of the reactions 118Sn(d, t) and 98Mo(d, t): (I). Spectroscopy of 117Sn and 97Mo

The vector analyzing power and differential cross section have been measured at a deuteron energy of 12.0 MeV for 118Sn(d, t) transitions to six states of 117Sn (Ex = 0.0, 0.16, 0.31, 0.71, 1.02 and 1.18 MeV), for 98Mo(d, t) transitions to eight states of 97Mo (Ex = 0.0, 0.68, 0.72, 0.89, 1.12, 1.28, 2.39 and 2.52 MeV), and for 118Sn(d, d)and 98Mo(d, d). Deuteron optical model potentials were obtained from analysis of the elastic scattering measurements, and were used in a DWBA analysis of the (d, t) results. Comparison of the measurements and DWBA predictions for σ(θ) and for iT11(θ) allows unambiguous determination of tln and jn for all 118Sn(d, t) and most 98Mo(d, t) transitions. Differences in the triton energy relative to the Coulomb barrier cause marked qualitative differences in the measured cross sections and analyzing powers between 118Sn(d, t) and 98Mo(d, t) transitions of the same ln and jn.
