## TL;DR

This study measures and analyzes elastic, inelastic, and transfer reaction cross sections for the $^{10}$B+$^{120}$Sn system near the Coulomb barrier, combining experimental data with coupled reaction channel calculations for comprehensive understanding.

## Contribution

It provides new experimental cross section data and applies CRC calculations with the São Paulo potential to describe reaction mechanisms near the Coulomb barrier.

## Key findings

- Good agreement between experimental data and CRC calculations.
- Couplings to inelastic and transfer states significantly affect elastic scattering.
- Continuum couplings also influence the scattering distributions.

## Abstract

The $^{10}$B+$^{120}$Sn reaction has been systematically studied at laboratory energies around the Coulomb barrier: E$_{\rm LAB}=$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.
