Energy dependence of theSn124(p, t)reaction to the3−-10+two-quasiparticle states ofSn122at incident energies of 34.9, 45.1, 54.7, and 65.0 MeV

Angular distributions for the ${}_{}{}^{124}{}_{}{}^{}\mathrm{Sn}(p, t)$ reaction to low-lying $3^{-}$, $4^{+}$, $5^{-}$, $6^{+}$, $7^{-}$, $8^{+}$, and ${10}^{+}$ two-quasiparticle states of ${}_{}{}^{122}{}_{}{}^{}\mathrm{Sn}$ were measured at $E_p=34.9, 45.1, 54.7, \mathrm{and} 65.0$ MeV and analyzed with zero-range distorted-wave Born approximation theory. The shapes of the angular distributions are reasonably well reproduced with the zero-range theory using one average optical potential set and the deduced enhancement factors are almost constant with smoothly decreasing zero-range normalization constants as a function of the incident energy.
