Abstract
In view of potential applications to the normal incidence optics we calculated the optical constants of metals Sc, Ti, V, Cr and Fe in the interval $HBAR(omega) less than or equal to 70 eV. The calculation was carried out within frames of the band structure approach with the use of the linear muffin-tin orbitals (LMTO) method and taking into account electron excitation of the nearest core levels. Obtained dielectric function shows good agreement with experimental spectra of the absorption (mu) ((omega) ), the reflectivity R((omega) ) and the electron energy loss spectroscopy (EELS) L((omega) ). The trends in optical spectra of metals along the 3d- series and mutual correlation of features of (mu) ((omega) ), R((omega) ) and L((omega) ) are considered and discussed.
