The angular distribution for the quasi-elastic scattering of the halo nucleus 11Be from 209Bi has been measured at 40 MeV beam energy. The measurement performed with a beam intensity of ~ 104 Hz could be done due to a ~ 4 pi array based on high granularity Si detectors. The 11Be (Sn = 0.504 MeV) angular distribution was found to be nearly equal to that of 9Be (S2 alpha +n = 1.574 MeV), i.e. with quite similar reaction cross section. This means that the influence of low binding energy and/or halo structure onto reaction dynamics has to be better understood.
