Investigations of Cluster Effects in Atomic Nuclei

  • 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NZ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 NZ 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.
