Abstract

SK alpha 1,2 and SK beta 1 fluorescence X-ray emission spectra of YBa2(CuO1-x(NiS)x) 3O4- delta (x=0.01; 0.03) are investigated. According to analysis of their energy position and fine structure one can conclude that sulphur atoms enter the lattice of Y123 compounds and form oxyanion groups. The oxidation state of S atoms in these compounds depends on their concentration and varies from 4+ to 6+.
