4f74f6+e charge fluctuations (inferered from Eu151 Mössbauer spectroscopy) in EuPd2Si2 show a strong nonlinear thermal dependence when compared to those observed in dilute Eu in LaPd2Si2. This nonlinear behavior is well described by extending the interconfigurational fluctuation model to include a cooperative intersite coupling of the interconfigurational fluctuation excitation energy to the 4f occupation number. Eu nuclear vibrational damping occurs in the region of greatest charge instability.
