Description
The structure of the light nuclei 6Li, 9,10,11,12Be, 10,11B, 12,13,14C, 13,14N and 14O were studied using the alpha-cluster model with hyperspherical functions and Feynman’s path integrals [1‒4] and the shell model of the deformed nuclei [5]. Results for the 12C and 9Be nuclei are shown in Figs. 1, 2.
Fig. 1. The regular triangle configuration in the alpha-cluster models (a) and the total neutrons probability density (logarithmic scale) for the 12C nucleus obtained in the shell model of a deformed nucleus (b)
Fig. 2. The total protons (a) and neutrons (b) probability densities (linear scale) for the 9Be nucleus obtained in the shell model of a deformed nucleus
The cluster transfer channels in the low energies nuclear reactions [6, 7] are explained taking into account the cluster structure of the 9Be nucleus.
