    Notizen: 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.

    Notizen: Abstract The semiclassical interpretation of heavy ion reactions is discussed. It is found that deflection to negative angles is inconsistent with optical model calculations. Due to the uncertainty principle trajectories are not well defined if the reaction is localized at the nuclear surface. It is, therefore, suggested that quantum diffraction is the dominating physical process for oscillating heavy ion transfer reactions.
