Quantitative analysis of (3He,t3He,t) charge exchange reactions at 140 MeV/u beam energy
Abstract
Composite particle, (3He,t)(3He,t), charge exchange reactions on targets 12C12C, 13C13C, 18O18O, 26Mg26Mg, 58Ni58Ni and 118,120Sn118,120Sn 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 12C12C.
