Abstract

The results of experiments on studying nucleon and cluster transfer processes in the reactions of the ⁶Li (68 MeV) ions with the ⁹Be target nuclei are presented. The angular distributions for the reaction channels ⁹Be(⁶Li,α)¹¹B_g.s and ⁹Be(⁶Li,¹⁰B)⁵He_g.s. have been measured. To describe the possible contributions of sequential transfer of nucleons and alpha clusters, as well as direct transfer of the ⁵Не cluster, the DWBA method (FRESCO) is used, the spectroscopic amplitudes are obtained for the configurations of (⁹Be+d) and (⁶Li+⁵He) in the ¹¹B nucleus and (⁶Li+α) in the ¹⁰B nucleus. The results of the theoretical analysis agree with the experimental data and indicate a strong correlation between a neutron and an α-cluster, leading to the formation of the ⁵Не cluster in the transfer processes.
