类Ne La离子的3—2跃迁及其伴线结构的理论研究

THEORETICAL STUDY OF SPECTRA OF 3-2 TRANSITION AND ITS SATELLITE LINES FOR Ne-LIKE ION OF La

在对类Ne La离子及其近邻的类Na、类Mg和类Al离子的n=3—n=2跃迁的波长和跃迁几率详细计算的基础上,考虑了等离于体中单个谱线的展宽和谱线之间的重叠.在高温条件和局部热动平衡近似下,得到了这些电离态离子同时存在时产生的具有带状分布特征的谱带的中心波长和半最大全宽度.解释了已有的实验结果。

Based on the calculated wavelengths and transition probabilities of n-3 to n-2 transitions for Ne-like, Na-like, Mg-like and Al-like ions of La, in the case of high temperature condition and local thermodynamic equilibrium approximation, we simulated the spectral structure of all the charged states by considering the broadening of individual line and overlapping of a large number of lines in plasma, presented the mean wavelengths and half width of the satellite peaks, interpreted the previous experimental spectral structures, and predicted some new satellite peaks in a larger wavelength region.
