摘　　要：利用全实加关联(FCPC)方法计算了类锂V20+离子的激发态1s2nd(n≤9)的非相对论的电离能;将相对论效应和质量极化效应作为一级微扰,计算了它们对体系能量的修正;利用有效核电荷方法计算了电子的量子电动力学(QED)效应对电离势的贡献.为了得到高精度的理论结果,还考虑了离子实修正和高角动量分波对能量的贡献.在用FCPC方法得到的V20+离子的激发态能量的基础上,以单通道量子亏损理论(QDT)为依据,计算了Rydberg系列的量子数亏损;将得到的量子数亏损作为输入,又实现了对任意高激发态的能量的理论预言.The nonrelativistic ionization potentials of 1s2nd states（n≤9） for the lithium-like V20＋ ion are calculated using the full-core plus correlation（FCPC） method.And the relativistic effects and mass polarization effects are evaluated as the first-order perturbation corrections for the energies of the system.The quantum-electrodynamics（QED） corrections are evaluated by using effective nuclear charges.For obtaining the high-precision theoretical results,the corrections of core and the higher l contributions to the energies are also calculated.On the basis of the energies of excited states for lithium-like V20＋ ion obtained by FCPC method,and based on the single channel quantum defect theory,the quantum defects of the Rydberg are calculated.With the quantum defects obtained in this work as input,the accurate predictions makes it possible to predict the highly excited energies of the system.
