Evidence for Strong Inelastic Processes in (p,t) Reactions on Deformed Nuclei

Large deviations between distorted-wave Born approximation predictions and measured ${}_{}{}^{186}{}_{}{}^{}\mathrm{W}\mathrm{}(p,t)\mathrm{}$ reaction cross sections are explained by inelastic excitations in the entrance and exit channels when the reaction is treated by means of a coupled-channel calculation. The results presented include transitions to the ground-state, $\beta$ vibrational, and $\gamma$ vibrational bands of ${}_{}{}^{184}{}_{}{}^{}\mathrm{W}$. The presence of inelastic processes is shown to result in significant differences in angular distributions representing the same transferred angular momentum.
