$ $An experiment has been carried out for studying the cluster structure of $^9$Be induced by the $^3$He ions at the energy of 30 MeV. As results of the nuclear reaction $^3$He + $^9$Be the differential cross sections for the exit channels - elastic, inelastic, $\alpha$ + $^8$Be, $^6$He + $^6$Be, $^6$Li + $^6$Li, and $^7$Be + $^5$He - were measured. Elastic and inelastic scattering data are treated within both the optical model and Coupled channels method. A new set of optical potential was taken for the elastic scattering. The deformation parameter $\delta_2$ was established for the transition $3/2\rightarrow5/2$. Cluster transfer reactions are analyzed by means of the coupled reaction channels method. The nuclear reactions with the exit channels $^6$He + $^6$Be, $^6$Li + $^6$Li, and $^7$Be + $^5$He are complemented by two-step transfer mechanisms. The contribution of each reaction mechanisms are shown, and compared with the findings of other authors.
