Understanding the mechanisms of nuclear collisions: A complete study of the 10B+120Sn reaction

Background: Reactions involving exotic and stable weakly bound nuclei have been extensively studied in recent years. Although several models have been successfully used to explain particular reaction outcomes, the answers to many questions remain elusive. In previous works, we presented elastic, inelastic, and transfer angular distributions for the B-10 + Sn-120 system measured at E-Lab = 31.5, 33.0, 35.0, and 37.5 MeV. The data set was analyzed through coupled reaction channels calculations in the context of the double-folding Sao Paulo potential. Purpose: We investigate nuclear reaction mechanisms for systems involving weakly bound projectiles. Method: Angular distributions for several nuclear reaction processes were measured for the B-10 + Sn-120 system at E-Lab = 39.70 MeV. Results: The new data set involves angular distributions for elastic scattering, projectile and target inelastic excitations, one-neutron pickup transfer, one-proton stripping transfer, deuteron pickup transfer, and He-3,He-4 stripping transfer. We have also observed Be-10 nuclei. The effect of the couplings to some nonelastic states on the angular distributions is discussed. Conclusion: The theoretical calculations within the coupled reaction channels formalism provide an overall good agreement with the corresponding inelastic, one-neutron stripping, one-proton pickup, one-deuteron pickup, and He-3 stripping transfer data. However, to improve the description of the elastic scattering angular distribution, the inclusion of additional channels in the coupling scheme might be necessary.

Automated summary

The study focused on nuclear reaction mechanisms for systems involving weakly bound projectiles, analyzing angular distributions for various reaction processes and observing the presence of Be-10 nuclei. The effect of couplings to nonelastic states on angular distributions was discussed, and theoretical calculations showed good agreement with experimental data for inelastic, one-neutron stripping, one-proton pickup, one-deuteron pickup, and He-3 stripping transfer reactions. Further inclusion of additional channels may be necessary to improve the description of elastic scattering angular distribution.
