Abstract

K edge X-ray absorption spectral shapes can be detected by measuring the Kβ X-ray emission decay channel. Due to the coherence of the excitation and decay processes, the convolution of the spectral shape with the 1s life time broadening disappears. The increased resolution makes possible the study of electron correlation effects in the pre-edge peaks of K edges. Due to the 3p3d exchange interaction, the Kβ decay channel has separate peaks for spin-up and spin-down. This spin-selection is exploited in so-called local-spin-selective X-ray absorption. From its comparison with X-ray magnetic circular dichroism (X-MCD) it is possible to determine the energy dependence of the Fano factor. This is shown for MnP.
