介绍了近期关于原子核结团效应的研究。利用Tohsaki-Horiuchi-Schuck-Ropke(THSR)波函数研究了~(20)Ne和~(9,10)Be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~(9,10)Be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。
The recent research on nuclear clumping effect is introduced. The cluster structure of nuclei such as ~ (20) Ne and ~ (9,10) Be was studied by using the Tohsaki-Horiuchi-Schuck-Ropke (THSR) wave function. The study found that a single THSR wave function can describe the atomic cluster state. Using the hybrid-THSRBrink wave function, we found the non-localized kinetic properties of the nuclear clusters. Expand the THSR wave function and make it possible to apply it to the nucleus of N ≠ Z. This wavefunction correctly reproduces the nuclear orbital structure in the lower energy levels of ~ (9,10) Be isotopes. The α-decay process in proton / neutron nuclei is also discussed. The study found that proton / neutron skin has a significant effect on the α-decay life.
