Abstract
Intraionic spin-orbit-split multiplet levels have been observed by electronic Raman scattering in the intermediate-valence compound Eu . From the temperature dependence of the Raman peak positions and widths the interconfigurational excitation energy and an upper limit of the interconfigurational mixing width , respectively, have been obtained. This is the first spectroscopic support for the underlying assumptions of the ionic interconfigurational fluctuation model that has been proposed to describe intermediate valence.
