摘　　要：用HartrceFockRelativistic(HFR)自洽场方法,计算类锂铝离子1s2nl(n=2～7,l=0～5),1snln′l′(n,n′=2～3;l,l′=0～2)各能级值,电偶极跃迁谱线的光谱线性质(波长、振子强度和跃迁几率),其波长计算值和现有文献结果符合得较好。特别是实验中已观察到的软X射线激光跃迁(3d-4f,3d-5f)In this paper, by Hartree Fock Relativisitic (HFR) Self consistent field method, calculation of Li like Al ion energy levels in configurations 1s 2nl(n=2～7,l=0～5),1snln′l′(n,n′=2～3;l,l′=0～2) is made and Ab initio AlXI wavelengths below 40nm involving electric dipole transition (EI) between the energy levels of above the configurations are reported. Corresponding transition probabilities and oscillator strengths are given. The accuracy of wavelength calculation is better than 1% in all cases where existing data allow for comparison. The calculated wavelengths of Al 3d-4f, 3d-5f transition are in good agreement with the observed transition wavelengths at which soft X ray lasers have been experimentally demonstrated.
