Elastic-scattering processes in the $${}^{3}\textrm{He}+{}^{9}$$
Be reaction are studied on the basis of the 2
$$\alpha+n$$
three-body cluster model of the $${}^{9}$$
Be nucleus. The $${}^{9}$$
Be three-body wave function obtained by the variational method in the Gaussian basis is used to derive an analytic representation of nuclear-matter density distribution. The interaction potential calculated for the $${}^{3}\textrm{He}+{}^{9}$$
Be system by the double-folding method is employed to analyze experimental data on the differential cross section for the elastic-scattering process $${}^{9}$$
Be (

$${}^{9}$$
Be at collision energies between 30 and 60 MeV.
