Nuclear Structure With the Dinuclear Model

Abstract

The dinuclear system concept is applied to the explanation of the structure of nuclei. Hyperdeformed nuclei are assumed as dinuclear systems which could directly be excited in heavy ion collisions. Signatures of hyperdeformed states in such reactions could be γ-transitions between these states and their decay into the nuclei forming the hyperdeformed nucleus. The appearance of a low-lying band with negative parity states near the ground state band in actinide nuclei is explained by oscillations of the dinuclear system in the mass asymmetry coordinate. The results for the parity splitting and electric multipole moments in alternating parity bands in actinide nuclei are in agreement with experimental data.
