A variety of charge-exchange reactions involving complex particles has been used to study the response of a nucleus to a spin–isospin probe. The reactions have been the (3He, t) reaction, the (d, 2He) reaction, and reactions with the heavy ions 12C, 14N, 16O, and 20Ne as beam and charge exchange both ways. With all reactions, transitions are observed to the low-lying giant-resonance region, the quasi-elastic region, and the Δ region. With the (d, 2He) reaction, the spin structure of the response is studied.

The nuclear isotopic structure can be understood easily via the intermediate-energy charge exchange reactions of (p, n) and [Formula: see text]He, [Formula: see text] type. In the current contribution, we present some results for charge exchange reactions induced by 3He on targets lying in mass region [Formula: see text] 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.
