摘要: 介绍了近期关于原子核结团效应的研究。利用Tohsaki-Horiuchi-Schuck-Röpke（THSR）波函数研究了²⁰Ne和^9，10Be等原子核的结团结构。研究发现单个的THSR波函数即可很好地描述原子核的结团态。利用hybrid-THSRBrink波函数，发现了原子核结团的非局域化动力学性质。拓展了THSR波函数并使其能够应用于N≠Z的原子核之中。这一波函数正确地重现了^9，10Be同位素的较低能级中的核分子轨道结构。还讨论了丰质子/中子原子核中的α-衰变过程。研究发现质子/中子皮对α-衰变寿命有显著影响。


We introduce our recent works on the clustering effects in atomic nuclear systems. The clustering structures for ²⁰Ne and ^9,10Be isotopes are studied with the Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function. It is found that a single THSR wave function can provide good description for the cluster state. The nonlocalised aspect of cluster dynamics is discovered with the hybrid-THSR-Brink wave function. Extensions are made for the THSR wave function to enable studies of N≠Z nuclei. The nuclear molecular orbit structures in low lying states of ^9,10Be isotopes are correctly reproduced with this wave function. We also discuss the α-decay processes for proton/neutron-rich nuclei. The effect of proton/neutron skin is found to be considerable on α-decay half-life.
