The main purpose of this research is to study the nature of resonance states in the 6Li nucleus, and effects of cluster polarization on the spectrum of bound and resonance states. The cluster polarization is associated with changes of the size and shape of clusters (interacting nuclei) as they approach each other. To achieve these goals, a microscopic three-cluster model is used. This model takes into account two three-cluster configurations: 4He+p + n and 3H+d + p, which are then projected into four binary channels: 4He+d, 5He+p, 5Li+n, and 3H+3He. These three-cluster configurations made it possible to describe more precisely the internal structure of the d, 5He, 5Li, and 3He clusters, and to take into account their polarizability. It is shown that the used model reproduces well the spectrum of low-lying states of 6Li. It is found that cluster polarization strongly affects the structure of the bound and resonance states, and significantly changes their energy and width.
