摘要：

The Goldstone-Feynman diagrammatic technique is adopted to study the interaction between mixed-valent rare-earth impurities in BCS superconductors. The influence of cerium-impurity coupling together with isolated cerium-impurity upon superconductivity of Th1-xCex system is worked out. In comparison with magnetic rare-earth impurities, depression of superconductivity due to impurity interaction of nonmagnetic mixed-valent rare-earth dopants is much smaller.
