摘　　要：依据离子能级的相对论量子亏损理论,给出了类氦离子电离能的一种表达式。根据原子序数6至15的类氦离子电离能的实验数据,对其电离能表达式中的量子数亏损及屏蔽电荷数进行了拟合,得到类氦离子电离能与原子序数的关系式,依据该关系式计算的电离能理论值与已有实验值符合得很好。推算了原子序数16至39的类氦离子的电离能,并与其他方法的计算结果进行了对比分析。Based on relativity quantum defect theory of ions energy levels,an expression of ionization energies of helium-like ions has been given.Based on the experimental data of ionization energies of helium-like ions from Z=6 to 15,the quantum defect number and the shielding charge number in the expression has been given by using curve fitting,so the relationship of ionization energies and atomic number has been given.The ionization energies of lithium-like ions based on the relationship is consistent with the experimental data.The ionization energies of lithium-like ions from Z=16 to 39 has been calculated and were compared the calculated results with other methods＇.
