“…The obtained electron energy spectrum, as seen, has a simple, nearly free-electron character. Qualitatively, it is similar to the Stark and Falicov bandstructure [8], which was calculated with an account of nonlocal pseudopotentials, and to the recent Wedig et al bandstructure [23] calculated by DFT technique. The main difference in the presented hypothetical and Stark-Falicov bandstructures, from the point of view of optical transitions, is in the values of the band gaps at the L-point.…”

“…When the strong parallel-band effects in interband optical absorption of metals were revealed by Ehrenreich et al [5] and Harrison [6] and the first calculations of the band structure of Zn were carried out [7,8], the optical studies of Zn focused on the NIR-VIS spectral range, where optical features due to interband transitions were soon revealed by Graves and Lenham [9] and later were confirmed by numerous subsequent investigations [10][11][12][13].…”

“…The Stark and Falicov band structure calculations [8] were carried out in a framework of the nonlocal pseudopotential technique with parameters adjusted to fit the de Haasvan Alphen experimental data on the zinc Fermi surface topology. However, the theoretical calculations [14] of Zn optical conductivity, based on the predicted electron energy spectrum, yielded rather poor correspondence with experimental data with respect to both the positions and the intensities of the experimental absorption peaks.…”

Experimental results of an optical study of single-crystal zinc are presented. Components of the Zn dielectric function tensor were measured by spectroscopic ellipsometry in the 0.1-5 eV spectral range. In the NIR-VIS range, the dielectric function spectra show two clearly resolved, polarization-dependent optical features located at about 1 and 1.7 eV. The optical features were analyzed in a framework of parallel-band optical transitions. The performed theoretical calculations of the optical conductivity spectra well reproduce the experimental data with respect to positions, intensities, and polarization dependencies of the observed interband absorption peaks.

“…The peculiar dependence of both isotropic and anisotropic shifts has been attributed to the effects of lattice vibrations on the Cd band structure [13,14]_ In the pseudopotential approximation, the increasing phonon modulation of the band structure weakens the pseudopotential [15] of pure Cd, leading to a more free electron like behavior at the Fermi surface. The important parts of the Fermi surface insofar as the Knight shift is concerned are the sections of 2d-zone-hole monster in the fM direction and lens of the third band, which are a mixture of "s" and "p" like electronic states [14].…”

The c urrent th eoretical and experimental situation with respect to Knight shifts and bulk susceptibility of Cd in pure Cd and in Cd-Mg and Cd-Hg alloys is reviewed_ New experim ental isotropi c and anisotropic Knight shift data on 1I3Cd in Cd-Mg and Cd-H g alloys and on '""Hg in Cd-Hg alloys are presented_ Th e behavior of the '"9Hg sites is found to be rem arkabl y similar to that of the 1I3C d site in the Cd-Hg alloys. However th e ratio of isotropi c Kni ght S hift of I!!!lHg to 113Cd is so me what grea ter than the ratio of ,"9Hg to 1I3Cd atomic hyperfine fields suggestin g th at there is more local electronic "s" characte r at th e Fermi surface in the alloy than in th e pure metals _ This is consistent with th e theoretical picture of Cd in which phonon scattering indu ced by in creasing temperature or all oying smears and weakens the lattice pote ntial whi ch in turn leads to a more "s" like Fermi surface_ Furthe r, the 1I3Cd Knight shift is found to be a useful tool for monitoring the phase segregation that occurs in Cd-Mg due to internal oxidation and for determinin g the concentrations of solutes su ch as Hg and Mg in Cd-Hg and Cd-Mg alloys_
