Elastic scattering, inelastic excitation, and 1n pick-up transfer cross sections for ${}^{10}$B+${}^{120}$Sn at energies near the Coulomb barrier

The ${}^{10}$B+${}^{120}$Sn reaction has been systematically studied at laboratory energies around the Coulomb barrier: E${}_{\mathrm{L}\mathrm{A}\mathrm{B}}=$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 ${}^{10}$B; excitation to the $2^{+}$ and $3^{-}$ states of ${}^{120}$Sn; and the one-neutron pick-up transfer ${}^{120}$Sn(${}^{10}$B,${}^{11}$B)${}^{119}$Sn. Coupled reaction channel (CRC) calculations have been performed in the context of the double-folding S~ao 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.
