| 摘 要： | 以相对论多体微扰理论为基础，利用屏蔽理论的思想和方法，引入并改进了与核电荷数Z相关的能量修正函数，计算了CⅠ等电子序列离子（6<=Z<=55）基组态(1s2 2s2 2p2)和第一激发组态(1s2 2s2 2p1)能量.计算过程基于自编的C语言和Mathematica程序，所得结果与实验值符合的很好，大大减小了由于忽略能量高阶项产生的误差，证明此项改进适用于等电子序列离子组态能量的计算.

| Abstract: | Based on the relativistic many-body perturbation theory(RMBPT) and screening theory for many electron atomic system, the energies of C-like sequence ions(6<=Z<=55) for ground configuration(1s2 2s2 2p2) and the first excited configuration(1s2 2s2 2p1) are calculated. An improved Z-dependent modify function is introduced to increase the accuracy of the result, which makes it excellent agree with the available experimental data. C and Mathematica programs are designed for this calculation. The conclusion is obtained that this modification is suitable for the calculation of the configuration energies of isoelectronic sequence ions. |
