Popis:	We investigate properties of bound and resonance states in the Λ 9 Be nucleus. To reveal the nature of these states, we use a three-cluster 2 α + Λ microscopic model. The model incorporates Gaussian and oscillator basis functions and reduces a three-cluster Schrodinger equation to a two-body like many-channel problem with the two-cluster subsystems ( Λ 5 He and 8Be) being in a bound or a pseudo-bound state. Influence of the cluster polarization on the energy and widths of resonance states in Λ 9 Be and on elastic and inelastic Λ 5 He +α scattering is analyzed.
