This paper presents the results of experiments conducted to measure the cross-sections for elastic scattering and nucleon transfer channels in the 6Li+9Be reaction at an incident energy of 68 MeV: 9Be(6Li,6Li)9Be, 9Be(6Li,7Li)8Be, 9Be(6Li,7Li)8Be2+9Be(6Li,8Li)7Be, and 9Be(6Li,7Be)8Li. The objective of the study is to elucidate the manifestation of the cluster structure of 9Be. Theoretical analysis of the contributions of the one-step and two-step neutron transfer mechanisms is performed using the distorted wave Born approximation method with the Fresco code. Good agreement between the calculations and the experimental data is obtained for the channels of elastic scattering 9Be(6Li,6Li)9Be, neutron 9Be(6Li,7Li)8Be, and proton transfer 9Be(6Li,7Be)8Li, as well as for the transfer of two neutrons 9Be(6Li,8Li)7Be. The dineutron cluster transfer mechanism makes a dominant contribution to the 9Be(6Li,8Li)7Be reaction channel at forward angles.
