摘要
为弥补光谱数据在实验方面的空白,满足相关领域研究的需求,利用扭曲波波恩近似方法及AUTOSTRUCTURE(AS)程序,计算了类氖氩(Ar8+)离子2s22p53n、2s2 p63n(n=s、p、d)组态的光谱参数,预言了部分实验中尚未观测到的能级值.理论计算值与已有的实验值进行对比,吻合较好.从已有的实验值与理论计算值对比结果的高度准确性看,这些预测值是可信的.结果表明,采用扭曲波波恩近似并结合AUTOSTRUCTURE(AS)程序的研究方法,可以成为研究原子或离子碰撞激发光谱的途径.
In order to obtain the experimental data and meet the requirements of the research in the relevant field,the distorted wave Born approximation and AUTOSTRUCTURE（AS）program were used to calculate the collision excitation spectral data of some highly charged ions.The 2s22p53n、2s2 p63n（n=s、p、d）configuration of Ne-like Ar8＋ion was studied,and their atomic excited state autoionization spectra was calculated.The theoretically calculated results agreed very well with the experimental data.Their agreement shows that the predicted values are credible.The results indicate that the method which comhines the distorted wave Born approximation and AUTOSTRUCTURE（AS）program is a an effective way of studying the electron-impact excitations of complex atoms or ions.
