本文采用Hartree-Fock自洽场方法,从理论上计算了类锂氯离子和类锂钾离子可能实现软X射线激光的有关能级能量及跃迁谱线性质:跃迁波长、跃迁几率和振子强度。计算结果表明,类锂钾离子的部分跃迁非常有可能实现软X射线激光,并且其中有三条谱线的波长已进入水窗。

Transition wavelengths of 4d-3p, 4f-3d, 5d-3p, 5f-3d, 6d-3p and 6f-3d of Cl XV and K XVII are reported. Corresponding transition probabilities and oscillator strengths are given. These transitions are of potential interest for X-ray lasers with shorter wavelengths towards the "water window". Among them, wavelengths of three KXVII transitions are in the range of the "water window". They are 3p-5d, 3d-6f, 3p-6d.
