The study of inelastic scattering and multi-nucleon transfer reactions wasperformed by bombarding a $^{9}$Be target with a $^3$He beam at an incidentenergy of 30 MeV. Angular distributions for $^9$Be($^3$He,$^3$He)$^{9}$Be,$^9$Be($^3$He,$^4$He)$^{8}$Be, $^9$Be($^3$He,$^5$He)$^{7}$Be,$^9$Be($^3$He,$^6$Li)$^6$Li and $^9$Be($^3$He,$^5$Li)$^7$Li reaction channelswere measured. Experimental angular distributions for the corresponding groundstates (g.s.) were analysed within the framework of the optical model, thecoupled-channel approach and the distorted-wave Born approximation. Crosssections for channels leading to unbound $^5$He$_{g.s.}$, $^5$Li$_{g.s.}$ and$^8$Be systems were obtained from singles measurements where the relationshipbetween the energy and the scattering angle of the observed stable ejectile isconstrained by two-body kinematics. Information on the cluster structure of$^{9}$Be was obtained from the transfer channels. It was concluded that clustertransfer is an important mechanism in the investigated nuclear reactions. Inthe present work an attempt was made to estimate the relative strengths of theinteresting $^8$Be+$n$ and $^5$He+$\alpha$ cluster configurations in $^9$Be.The branching ratios have been determined confirming that the $^5$He+$\alpha$configuration plays an important role. The configuration of $^9$Be consistingof two bound helium clusters $^3$He+$^6$He is significantly suppressed, whereasthe two-body configurations ${}^{8}$Be+$n$ and ${}^{5}$He+$\alpha$ includingunbound $^8$Be and $^5$He are found more probable.
