A study of inelastic scattering and multi-particle transfer reactions was performed by alpha and 3He beams on a 9Be target at energy about 50 MeV. Angular distributions of the differential cross sections for the 9Be(α,α′)9Be*, 9Be(α,3He)10Be, 9Be(α,t)10B, 9Be(3He,6Li)6Li and 9Be(3He,6Be)6He reactions were measured. Experimental angular distributions of the differential cross sections for the ground state and a few low-lying states were analyzed in the framework of the optical model, coupled channels and distorted-wave Born approximation. The information on the cluster structure of the reaction products are obtained. An analysis of the obtained spectroscopic factors was performed.
