Charge exchange reactions on medium and heavy mass targets at intermediate energies
Abstract
The nuclear isotopic structure can be understood easily via the intermediate-energy charge exchange reactions of (p, n) and (3He, t) type. In the current contribution, we present some results for charge exchange reactions induced by 3He on targets lying in mass region 18≤A≤208 within the theoretical framework of plane wave impulse approximation (PWIA) and distorted wave impulse approximation (DWIA). Here, the recoil effects in PWIA have also been considered. Particularly, the angular distributions and the unit cross-sections have been calculated and compared with the available data. Further, the importance of inclusion of the exchange contribution in these reactions is also considered, which eventually enhance the matching with data.
