Breakup reactions may be considered by a quasi-three-body model in which the two-body subsystems interact through optical model potentials with imaginary parts describing the excitation of unobserved channels. The distorted wave off-shell impulse approximation neglects only gradients of the optical model potentials. At sufficiently high energies it factorizes into a quantity describing the elementary two-body collision and a distorted wave transform of the bound-state wavefunction, which gives a distorted orbital momentum profile. Examples showing the validity of the approximation are given.

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.

We have measured the angular distributions for 16 O elastically scattered on 12 C nuclei at energy 28 MeV and also for 12 C ion beam elastically scattered on 11 B target nuclei at energy 18 MeV. These measurements were performed in the cyclotron DC-60 INP NNC RK. Calculations were performed using both empirical Woods–Saxon and double folding optical model potentials. Both elastic scattering and transfer reaction were taken into consideration. We have extracted the spectroscopic factors for the configurations 16 O → 12 C + α and 12 C → 11 B + p and compared them with other calculated or extracted values at different energies from literature. The extracted spectroscopic factor for the configuration 12 C → 11 B + p from the current work is in the range 2.7–3.1, which is very close to Cohen–Kurath prediction. While for the configuration 16 O → 12 C + α, spectroscopic factors show fluctuation with energy which could be due to the well-known resonant-like behavior observed in 16 O + 12 C excitation function.
