The 9 ; 11Be+209Bi subbarrier fusion cross-sections were measured. The good quality of the 9Be data allowed also to extract the fusion barrier distribution. The data are in good agreement with the theoretical predictions above the barrier but not below, where the cross-sections are similar, in contradiction with present theories. The barrier distribution for 9Be does not evidence fusion processes originating from breakup.

Abstract
The 9 ; 11Be+209Bi subbarrier fusion cross-sections were measured. The good quality of the 9Be data allowed also to extract the fusion barrier distribution. The data are in good agreement with the theoretical predictions above the barrier but not below, where the cross-sections are similar, in contradiction with present theories. The barrier distribution for 9Be does not evidence fusion processes originating from breakup.
