Abstract

The 10B+120Sn reaction has been systematically studied at laboratory energies around the Coulomb barrier: ELAB=31.5, 33.5, 35.0, and 37.5 MeV. Cross sections for the elastic scattering and some reaction processes have been measured: excitation to the 1+ state of 10B; excitation to the 2+ and 3−states of 120Sn; and the one-neutron pick-up transfer 120Sn(10B,11B)119Sn. Coupled reaction channel (CRC) calculations have been performed in the context of the double-folding São Paulo potential. The theoretical calculations result in a good overall description of the experimental angular distributions. The effect on the theoretical elastic-scattering angular distributions of couplings to the inelastic and transfer states (through the CRC calculations) and to the continuum states (through continuum-discretized coupled-channels calculations) has been investigated.
