Theory of resonant X-ray emission spectroscopy.
A short review is presented of recent topics in resonant X-ray emission spectroscopy (RXES), especially of the polarization dependence of RXES in d and f electron systems. Polarization-dependent RXES provides important information on the symmetry of electronic states. A scattering-angle dependence in the fluorescence yield of rare-earth metals, RXES in polarized and depolarized configurations of TiO2, and the magnetic circular dichroism in RXES of ferromagnetic systems are discussed together with typical experimental data.
