摘　　要：采用基于多组态Hartree-Fock方法的Cowan程序计算了类锂离子(Z=3-18)的能级、跃迁能、跃迁波长和跃迁几率等原子结构参数。结果表明,从头计算的原子结构参数与NIST的推荐值存在一定的误差,用最小二乘法拟合后,与NIST的推荐值符合得非常好。计算结果表明最小二乘法拟合方法是可靠的。In this paper,based on the multi-configuration hartree-fock method,the Cowan program is used to calculate energy level,transition energy,transition wavelength,transition probability atomic structure parameters of Li-like ions(Z=3-18).The results show that there is a certain error between the ab initio calculated atomic structure parameters and the recommended value of NIST.The calculated atomic structure parameters are in good agreement with the recommended value of NIST after which are fitted by the least square method.The calculated results show that the least square fitting method is reliable.
