We investigate the change of the neutron-skin thickness from parent to daughter nuclei involved in the cluster decay process. The neutron-skin thickness is obtained using self-consistent Hartree–Fock–Bogolyubov calculations based on Skyrme-SLy4 effective nucleon–nucleon interaction. The experimental data of the cluster decay modes observed to date indicate that the shell effect then the released energy play the predominate role of determining the spontaneous cluster decay modes. The effect of the change in the neutron-skin thickness from parent to daughter nuclei comes next to them. The cluster decay preferably proceeds to yield the least possible increase in the neutron-skin thickness of the daughter nucleus (δ _n). δ _n decreases when the isospin-asymmetry of the emitted cluster increases. The relative stability of the radioactive nucleus and its corresponding partial half-life increase for the cluster decays leading to a significant increase in the neutron-skin thickness.

我们调查中子皮厚度从父核到子核参与团簇衰变过程的变化。使用基于Skyrme-SLy4有效核子-核子相互作用的自洽Hartree-Fock-Bogolyubov计算获得中子皮厚度。迄今为止观察到的团簇衰减模式的实验数据表明，壳效应和释放的能量起着决定自发团簇衰减模式的主要作用。从母核到子核的中子皮厚度变化的影响紧随其后。群集衰变优选进行到产生在子核（的中子皮肤厚度的至少可能增加δ _Ñ）。δ _ñ当发射簇的同位旋不对称性增加时，其减小。原子团的放射性核的相对稳定性及其相应的部分半衰期的增加导致中子皮厚度的显着增加。
