Abstract

The photoexcited F Kα X-ray intensity's evolution was measured for CaF2 with fine energy-step from the [1s2p] double excitation threshold to the saturation region, where square brackets indicate hole states. The observed evolution was directly compared with the X-ray absorption spectrum, and the contribution of multielectron excitation to the absorption spectrum was successfully resolved. The F-K fluorescence XANES spectra were calculated based on the coherent second-order optical processes for comparison.
