Abstract The3He-elastic scattering and the (3He,t)-reactions on10B,11B and13C were studied. Excitation functions for the reactions10B(3He,t)10C and11B(3He,t)11C were measured at incident energies between 11 and 17 MeV. All angular distributions were taken at 14 MeV3He-energy. From an optical model analysis of the3He-elastic scattering data the parameters of the optical potentials were determined. Best fits were obtained using surface peaked potentials. The (3He,t)-reactions were interpreted in terms of a microscopic model, which, in general, gave a good account of the data. Corrections due to nonlocality effects were included in the calculations. A satisfactory agreement of the predicted and the measured cross sections required an effective nucleon-nucleon interaction of the Yukawa form (α−1=1.2 fm). Using a Serber exchange mixture the isospindependent- and the spin-isopin-dependent strength parameters of the potential were deduced to beVτ=21.4±2.3 MeV andV σ τ=19.5 ± 2.7 MeV, respectively.
