摘　　要：This paper presents the results of experiments conducted to measure the cross-sections for elastic scattering and nucleon transfer channels in the ^(6)Li+^(9)Be reaction at an incident energy of 68 MeV:^(9)Be(^(6)Li,^(6)Li)^(9)Be,^(9)Be(^(6)Li,7Li)8Be,^(9)Be(^(6)Li,7Li)^(8)Be_(2+),^(9)Be(^(6)Li,^(8)Li)^(7)Be,and ^(9)Be(^(6)Li,^(7)Be)^(8)Li.The objective of the study is to elucidate the manifestation of the cluster structure of ^(9)Be.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 ^(9)Be(^(6)Li,^(6)Li)^(9)Be,neutron ^(9)Be(^(6)Li,^(7)Li)^(8)Be,and proton transfer ^(9)Be(^(6)Li,^(7)Be)^(8)Li,as well as for the transfer of two neutrons ^(9)Be(^(6)Li,^(8)Li)^(7)Be.The dineutron cluster transfer mechanism makes a dominant contribution to the ^(9)Be(^(6)Li,^(8)Li)^(7)Be reaction channel at forward angles.
