摘要
先前用于中高原子序数 Z 元素的多电荷离子的电离势近似的半经验准经典方法被应用于原子序数范围在 \(85 \leqslant Z \leqslant 110\) 和电子数范围在 \(1 \leqslant {{N}_{e}} \leqslant 78\) 的元素离子。根据所发现的简单趋势,我们可以在两个小表格的基础上,对 NIST 表格中所有多电荷离子在所考虑的原子序数范围内的电离势进行相对精确(在 1-2% 的范围内)的多项式近似。结果表明,随着原子序数的增加,准经典近似的适用条件也有所改善。
Quasi-Classical Approximation of the Data on the Ionization Potentials of Multiply Charged Ions of the Superheavy Elements
The semiempirical quasi-classical method of approximation of the ionization potentials used earlier for multiply charged ions of the elements with medium and high atomic number Z is applied to ions of elements with atomic numbers in the range of \(85 \leqslant Z \leqslant 110\) and number of electrons in the range of \(1 \leqslant {{N}_{e}} \leqslant 78\). The discovered simple trends allow using a relatively accurate (to within 1–2%), based on two small tables, polynomial approximation of the available and lacking data on the ionization potentials in the NIST tables for all multiply charged ions in the atomic-number range under consideration. An improvement in the applicability conditions of the quasi-classical approximation with increase in the atomic number is demonstrated.
