Abstract:This study aims at assessing the thermal nuclei motion effects on the multipole transition channels involved in two core-level spectroscopies, X-ray Absorption Spectroscopy (XAS) and X-ray Raman Scattering (XRS). Temperature effects on the 1s → s monopole, 1s → p dipole and 1s → d quadrupole transitions are investigated using two reference systems for which we present original experimental data: α-Al2O3 at the Al K edge probed by XRS at room temperature and rutile TiO2 at the Ti K pre-edge probed by XAS at tem… Show more
