Complete characterisation of the crystal electric field in Ce Kondo lattices with resonant inelastic soft X-ray scattering

By means of resonant inelastic x-ray scattering at the Cu L 3 edge, we measured the spin wave dispersion along h100i and h110i in the undoped cuprate Ca 2 CuO 2 Cl 2.. The data yields

R6sumi: Etant donnd le caractbre bidimensionnel des materiaux lamellaires, les spectres d'absorption des rayons X sont trbs sensibles aux effets de polarisation qui

The S2 edge inflection exihibits a shift to higher energy by about 1 eV and occurs at -6552.5 eV which is between that observed for Mn(III) and Mn(1V).. The lower K-edge

- Due to the attractive potential of the core hole a 4f level, unoccu- pied in the initial state, is lowered below the F e d level in the final state. De- pending on

l/he presence of large easily observable chemical effects in soft X-ray spectra means that such spectra can be used [6] in chemical speciation and because of their nanometer range,

- The following results of the experimental and theoretical investigations of the spectral behavior of the photoionization cross sections in the ultrasoft X-ray region are

They have shown that near threshold the absorption spectra show big differences between the gaseous and solid state ; for energies of 10 eV or more above threshold
