Very strong double-electron excitations have been observed for the first time in the W, Ir L 3-edge and Cs L 1,2,3-edges X-ray-absorption spectra of tungsten and iridium oxide thin films and cesium oxide containing glasses. They are expressed as peaks with a width of several electron-volts located at the absorption background above the edge. The positions of these features are in good agreement with atomic calculations in the Z+1 approximation. They can be attributed to the transitions 2p4d → 5d5d for the L 2,3-edges and 2s4d → 6p5d for the L 1-edge with the dipole selection rules for the angular and total angular momentum ΔL=±1, ΔJ=0,±1.
