Suppression of complete fusion due to breakup in the reactions ${}^{10,11}$B + ${}^{209}$Bi

Abstract

Above-barrier cross sections of $\alpha$-active heavy reaction products, as well as fission, were measured for the reactions of ${}^{10,11}$B with ${}^{209}$Bi. Detailed analysis showed that the heavy products include components from incomplete fusion as well as complete fusion (CF), but fission originates almost exclusively from CF. Compared with fusion calculations without breakup, the CF cross sections are suppressed by 15% for ${}^{10}$B and 7% for ${}^{11}$B. A consistent and systematic variation of the suppression of CF for reactions of the weakly bound nuclei ${}^{6,7}$Li, ${}^9$Be, ${}^{10,11}$B on targets of ${}^{208}$Pb and ${}^{209}$Bi is found as a function of the breakup threshold energy.
