摘要：
Reflectivity spectra of single crystals of Ca, Ba and Pb tungstates in the energy range 4-30eV are presented. Anisotropy of scheelite structure is studied on this set of crystals for their different orientations using polarised synchrotron radiation. Common features of the spectra are discussed in terms of electronic transitions within molecular complex WO4. (C) 2001 Elsevier Science B.V. All rights reserved.
