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