摘要：

Polarized reflectivity spectra of single-crystal TaSi2 have been neasured in the photon-energy range 0.6-20 eV to examine the electronic structure. An anisotropy has been definitely found below 12 eV. The complex dielectric functions and the optical conductivities are determined by Kramers-Kronig analysis. The spectral structures are discussed in terms of interband transitions among Ta 5d states and Si 3s-3p states, in comparison with published results on the density of states. The effective numbers of electrons contributing to optical transitions are also discussed.
