Specific features of 4 He interaction with light 9 Be nuclei are studied. The potential of 4 He– 9 Be interaction is calculated within the framework of the double folding model using the wave function of the ground state of the 9 Be nucleus constructed in the three-cluster α + α + n approximation. The differential cross sections of elastic and inelastic 4 He– 9 Be scattering and single-nucleon transfer in the intermediate range of energies are calculated. Comparative analysis of experimental and calculated results demonstrate their good agreement, indicating that the model assumptions on the cluster structure of 9 Be nucleus are valid.
