Four-body Microscopic Cluster Model Calculation of 7Li and 7Be Nuclei
Understanding deeply the properties of the ground and excited states of 7Li and 7Be is important for explaining the creation and related reactions of Li and Be isotopes in the primordial universe.Most of the cluster model calculations of 7Li or 7Be consider only the α+t or α+3He two-body cluster structure.The present work conducted theoretical research employing a four-body microscopic cluster model.The results show that,by considering the three-and four-body cluster structures,the cal-culated wave functions of ground and excited states are effectively modified.The obtained observables such as energy spectra and nuclear radii reproduce better the experimental data,compared to that in the two-body calculation.
