摘　　要：采用鞍点变分方法和鞍点复数转动方法,并考虑相对论修正、质量极化效应,计算了类锂等电子系列(Z=10～20)1s^2s^(22)S态的电离势、Auger跃迁率和辐射跃迁率.同时还计算了QED效应和高阶相对论修正对电离势的贡献.Abstract： The ionization potential, Auger transition rates and radiative rates of the 1s2s^22S states for Z=10 to 20 are calculated using the saddle-point variational method and the saddle-point complex-rotation method. Relativistic correction and mass polarization effects are included using first-order perturbation theory. The QED and higher-order relativistic contributions to the ionization potential are calculated using effective nucleus theory. Key words, lithiumlike ions, ionization potential, Auger transition rate

关 键 词：类锂离子 电离势 Auger跃迁率
