The 10 B + 120 Sn reaction has been investigated at E Lab = 37.5 MeV. The cross sections for different channels, such as the elastic scattering, the excitation of the 2 + and 3 − 120 Sn states, the excitation of the 1 + state of 10 B, and the 1n pick-up transfer, have been measured. One-step distorted-wave Born approximation and coupled-reactionchannels calculations have been performed in the context of the double-folding São Paulo potential. The effect of coupling the inelastic and transfer states on the angular distributions is discussed in the paper. In general, the theoretical calculations within the coupled-reaction-channels formalism yield a satisfactory agreement with the corresponding experimental angular distributions.
Elastic scattering angular distributions of the radioactive weakly bound 7 Be on 27 Al have been measured at energies near the Coulomb barrier. The interaction optical potential is investigated by using different potentials. Total reaction cross sections have also been obtained.
We present new experimental angular distributions for the elastic scattering of 6 Li + 120 Sn at three bombarding energies. We include these data in a wide systematic involving the elastic scattering of 4,6 He, 7 Li, 9 Be, 10 B and 16,18 O projectiles on the same target at energies around the respective Coulomb barriers. Considering this data set, we report on optical model analyses based on the double-folding São Paulo Potential. Within this approach, we study the sensitivity of the data fit to different models for the nuclear matter densities and to variations in the optical potential strengths.
