Description

The study of the cluster structure of light nuclei is one of the fundamental problems of nuclear physics. The cluster structure of $^6\text{Li}$ nucleus was a subject of many experimental and theoretical studies, for example [1-3]. The cluster configurations of $^6\text{Li}$ excited states can be either two-cluster ($^4\text{He}+d$, $^5\text{He}+p$, $^5\text{Li}+n$, $^3\text{He}+t$), or three-cluster ($^4\text{He}+p+n$) ones.
To determine the contribution of various configurations to the structure of excited states, we propose the study of inelastic scattering of $\alpha$-particles on the $^6\text{Li}$ nucleus, provided that the scattered $\alpha$-particle coincides with the particle from the breakup of the excited state. Kinematical simulation of this reaction was performed at $E_{\alpha} = 30$ MeV for various excited states of $^6\text{Li}$ nucleus. The simulation results show that registration of the scattered $\alpha$-particle in coincidence with various particles ($n, p, t, \alpha$) from the breakup of excited $^6\text{Li}$ states will allow us to determine the cluster structure of these states.
