| 摘 要： | 基于相对论连续谱Hartree-Bogoliubov(RCHB)理论,在NL-SH参数下,研究了从质子滴线到中子滴线Er偶同位素链的基态特性,计算的核结合能和核均方根半径,在有实验数据进行比较的范围内,与实验数据值符合较好。计算结果显示:在中子数为N=82-126的壳层里,在84-92、94-126之间有明显的子壳层结构;62582Er184核是中子滴线核。

| Abstract: | We study the ground state properties of even Er isotopes, from the proton drip line to the neutron drip line, in the Relativistic Continuum Hartree-Bogoliubov theory with the NL-SH parameters. The results show that theoretical binding energies and nuclear root mean square radii are in good agreement with the available experimental data. The following conclusions have been showing by investigating the calculated results: 1. within the neutron shell on N=82~126, there is an obvious sub-shell between the ranges of N=84~92 and N=94~126; 2. the predicted neutron drip line nucleus is 252 68Er184. |
