摘要：

Calculations of the effect of intermediate bosons on the optical properties of the normal state are used to analyze the spectra of these bosons. For high temperature superconductors these spectra are in agreement with the standard electron-phonon model (the end of the spectrum is near 800 cm(-1)) with a moderate coupling constant lambda=1-1.5. For the heavy fermion compound UPt3 the spectrum of intermediate bosons is consistent with neutron data for spin fluctuations.
