摘要
Measurements of the 6 Li + 9 Be collision above the Coulomb barrier ( E lab = 11 . 2 MeV; V lab Cou = 3 . 2 MeV) were performed using the 6 Li secondary beam selected by the RIBRAS (Radioactive Ion Beams in Brasil) first solenoid. The total reaction cross section was obtained from the 6 Li + 9 Be elastic scattering angular distribution, measured in the same experiment and analyzed by optical model calculations [U. Umbelino et al. , Phys. Rev. C 106 , 054602 (2022)]. Proton, deuteron, triton, and alpha yields were measured at angles around 45 degrees in the laboratory and total fusion cross sections were deduced from the comparison between compound nucleus calculations and the measured light particle yields. The difference between the total reaction cross section and the obtained total fusion cross section provided an estimation of the contribution from other direct reaction mechanisms such as elastic and nonelastic breakup.
