Bunching of cerium valence in mixed-valence compounds
Shaburov V. A., Smirnov Yu. P., Sovestnov A. E., Tyunis A. V.
Experiments reveal that cerium has a valence ~3.13, —3,27, or —3.39 in intermetallic compounds of mixed valence. The effect is explained on the basis that the different valence values correspond to different final states of a 4f electron. It may be possible to use this bunching effect to identify the final state of the 4/ electron in a mixed-valence phase.
