Abstract

Abstract:

Calculations of energy levels and radiative rates for Kα transitions among the lowest 40 fine-structure levels were introduced in Be-like ArⅩⅤ. The wavelengths, oscillator strengths, radiative rates and lifetimes for all possible Kα transitions have been calculated using the multi-configuration Dirac-Fock method. The accuracy of the results is determined through extensive comparisons with existing laboratory measurements and theoretical results. These results can be used to analysis the previous experimental results and guide the design of the future experiments.

Key words: Wavelength, Energy level, Oscillator strength, Transition probabilities, Quantum electrodynamic

摘要：

介绍了类Be的ArⅩⅤ最低40个能级的能级精细结构。利用基于多组态Dirac-Fock方程，给出了类Be的ArⅩⅤ的Kα跃迁的能级、波长、振子强度和能级寿命。研究表明，当前所得的理论计算结果与实验值以及其它理论值符合很好，同时对于分析已有的实验结果和指导拟开展的实验也有一定的意义。
