  $ $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.
