| 摘 要： | 用多组态HFR方法计算了类Li等电子序列钙(Ca,Z=20)离子1s~2nl(n=2～6,l=0～5)组态的所有能级和电偶极跃迁的软X射线光谱,其中4f→3d,5f→3d及5d→3p、4d→3p由于其下能级跃迁速率较大,容易形成粒子数反转因而可作为激光跃迁,5f→3d、6f→3d跃迁已处于“水窗”波段,而4f→3d的激光跃迁(5.77nm)已为我们最近的实验所证实.并将我们的计算结果与其它理论计算和实验数据进行了比较.

| Abstract: | The Soft X-ray spectra and energy levels of the 1s2 nl(n = 2-6, l = 0-6) configurations for the Li-like Ca ion are calculated with the aid of the multi-configuration HFR program developed by Cowan. The results are discussed and compared with other theoretical and experimental values. The 3d-4ftransition (5. 77 nm) as a soft X-ray laser transition has been confirmed by our latest experiment. |
