Abstract The angular distributions of elastic scattering of 14 N ions on 10 B targets have been measured at incident beam energies of 21.0 and 24.5 MeV. Angular distributions at higher energies 38–94.0 MeV (previously measured) were also included in the analysis. All data were analyzed within the framework of the optical model and the distorted waves Born approximation method. The observed rise in cross sections at large angles was interpreted as a possible contribution of the α-cluster exchange mechanism. Spectroscopic amplitudes SA 2 and SA 4 for the configuration 14 N→ 10 B + α were extracted. Their average values are 0.58±0.10 and 0.81±0.12 for SA 2 and SA 4 , respectively, suggesting that the exchange mechanism is a major component of the elastic scattering for this system. The energy dependence of the depths for the real and imaginary potentials was found.
