Elastic electron scattering from 4N nuclei in the $\alpha$α-cluster model with dispersion
Abstract.The $\alpha$α-cluster model with dispersion has been developed for some 4N nuclei in the 2s-1d shell. The previously considered molecule-like configuration for the 24Mg nucleus is compared with the octahedron one. For the 32S nucleus both the cubic and bitetrahedron configurations are discussed. Molecule-like configurations with the 32S nucleus core and additional dumb-bell for the 40Ca nucleus are proposed. The structure of the 40Ca nucleus consisting of six $\alpha$α-clusters arranged in a octahedron outside of tetrahedron 16O core is also considered. The calculated charge form factors and root mean square radii of such nuclei are in a reasonable agreement with the available experimental data.
