Alpha scattering from ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ at ${\mathit{E}}_{\mathrm{\alpha }}$= 65 MeV is described in the coupled channel framework with phenomenological as well as folded potentials. The multipole components of the deformed density of ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ are derived from Nilsson model wave functions. Reasonably good agreements are obtained for the angular distributions of 3/$2^{\mathrm{-}}$(g.s.) and 5/$2^{\mathrm{-}}$(2.43 MeV) states of the ground state band with folded potentials. The deformation predicted by the model corroborates with that derived from the phenomenological analysis with potentials of different geometries.
