Narrow Results

Composite particle, ${(}^{3}He,t)$, charge exchange reactions on targets ${}^{12}C$, ${}^{13}C$, ${}^{18}O$, ${}^{26}Mg$, ${}^{58}Ni$ and ${}^{118,120}Sn$ at 140 MeV/u beam energy have been analyzed by employing distorted wave impulse approximation (DWIA). Specifically, unit cross-section and angular distribution have been calculated using normal optical model potential (NOMP) and single folding optical model potential (SFOMP) for both relativistic and non-relativistic cases. The sensitivity of present results on exchange terms has also been examined and it is pertinent to report here that the inclusion of these effects reduces the cross-section in magnitude up to 60%, which in turn brings it closer to the data except for ${}^{12}C$.
