Description
Soft x-ray absorption and resonant inelastic x-ray scattering are briefly introduced [1]. In 2p3d resonant inelastic x-ray scattering (RIXS) one scans through the 2p XAS edge and measures the low energy excitations, including phonons, magnons, dd-excitations and charge transfer [2].Recently we measured time-resolved XAS and RIXS using the PAL-XFEL source in Pohang [3,4]. The oxygen K edge and metal L edges of CuWO$_4$ and Fe$_2$O$_3$ have been measured in relation to their application as photo(electro)catalyst systems.
