Abstract

The ${}^{13}C$ (p,pn $)^{12}$ C reaction was studied at $E_{p}$ =35 MeV with an experimental arrangement which favored detection of p-n pairs in the ${}^{1}$ $S_{0}$ state. Measured cross section angular distributions were compared with those for the ${}^{13}C$ (p,d $)^{12}$ C reaction at the same incident energy. The two reactions show different angular distribution shapes, those for (p,pn) being more slowly decreasing at large angles. Coupled channel calculations which include continuum states of the p-n system reproduce angular distribution shapes and cross section magnitudes of both the (p,pn) and (p,d) data.
