Abstract : The work has demonstrated that band theory is capable of giving a reasonably accurate account of the optical conductivity of both simple and transition metals in an energy region from the onset of direct interband transition up to excitations of the order of 5-10 eV. Lifetime broadening effects become appreciable as the excitation energy increases, but the basic structure of the optical conductivity is determined by the one electron theory. Even in the ferromagnetic transition elements, there is no evidence from any of the properties studied here that d electrons are localized, or that many body effects are unusually large. The degree of agreement between band theory and experiment is about as large for ferromagnetic metals as it is for simple metals. (Author)
