Abstract

The Cu K_β/K_α intensity ratios have been measured for copper compounds of Cu₂O, CuO, Cu₂S, CuS, CuF₂ and CuCl₂ and high-T_c superconducting cuprates of Y(Ba_1-x Sr_x)₂Cu_3-0.21xMo_0.21xO_y with x=0 - 1. The large increase of Cu K_β/K_α intensity ratio in high-T_c superconductor relative to other copper compounds is interpreted as the increase of transitions from Cu valence band to Cu(1s) state, when Cu(3d) and O(2p) are highly hybridized. The decrease ofCuK_β/K_α intensity ratio with the increase of x in the high-T_c superconducting cuprates indicates both the Sr and Mo ions have negative input to the degree of hybridization of Cu(3d) and O(2p) bands.
