摘要/Abstract

摘要：

应用不可分辨跃迁阵(UTA)模型结合相对论多组态Dirac-Fock方法,对金激光等离子体0.40～0.62nm范围内的带状谱和线状谱的主要特征参数进行了计算和分析，理论计算值和实验结果较之于单纯用UTA模型计算所得结果符合得更好。研究表明，对于谱线数目较少而又稀疏的跃迁，基于线谱的单独计算对UTA模型进行修正是合理和必要的。

Abstract:

Unresolved transition array model and multi-configuration Dirac-Fock (MCDF) method are applied to calculate the line and band spectrum of laser-produced gold plasmas in the 0.40～0.62nm range. The better agreement between theoretical and experimental measurement compared with the results of the calculation only using the UTA model indicates that it is reasonable and necessary to correct the UTA model using MCDF method when the transition array contains only a few lines and the distribution of the lines are very thin.

Key words: Spectrum of M band for Au, UTA model, MCDF method.
