摘　　要：用最弱受约束电子势模型(w eakest bound e lectronpoten tia lm ode l,W BEPM)理论计算多价原子的R ydberg态能级和相应的量子数亏损。在W BEPM理论框架下,对于一个类光谱能级系列,能级只是主量子数n的函数,通过区分最弱受约束电子与非最弱受约束电子,归纳出相应的类光谱系列,将M artin关于单价原子量子亏损的公式推广到了多价原子系统。以此计算的R u原子的4d7(4F)ns(n≥28)和4d7(4F)nd(n≥26)两个R ydberg系列的能级值与实验值的相对误差均在1.71×1-0 5之内,二者符合较好。这为计算多价原子体系R ydberg态能级提供了一个简捷有效的方法。The Rydberg energy levels and quantum defects of mulTi-valence atoms were calculated based on the weakest bound electron potential model （WBEPM）. The atom energy levels were expressed as a function of principal quantum number in the WBEPM theory, The Martin formula for the quantum defect of single valence atoms was extended to multi-valence atoms by separating the weakest hound electron and the non-weakest bound electrons in atoms, The Rydberg energy levels were then calculated for the 4d7 （^4F）ns （n ≥ 28） and 4d^7（^4F）nd （n≥26） Ru atoms. The maximum relative error between the calculated and measured values was 1.71× 10^-5. Therefore, WBEPM can be adopted to calculate the Rydberg energy levels of multi-valence atoms.
