Reactions of a 16.8 MeV He-6 beam with a Be-9 target have been investigated using highly segmented detector setup covering a large solid angle. Data on elastic and quasi-free scattering, as well as two-neutron transfer, are reported. The results for elastic scattering are fairly well reproduced by a CDCC calculation, in agreement with the interpretation of a breakup effect already observed for the scattering of He-6 on other light targets. Exotic quasi-free scattering of He-6 on alpha-cluster in Be-9 is clearly observed. Inclusive and coincident events were used to extract information on the two-neutron transfer reaction Be-9(He-6, alpha)Be-11. Sequential decay of the Be-11 state at the excitation energy E-x = 10.6 MeV through different channels is discussed.
