In both cases, the prominent features correspond largely to 共1兲 a nonlocally screened d-intersite ZRS 共d 9 L兲 feature at 2.2 eV, where the core hole has pushed a d 9 hole from

Then we specialize to those terms responsible of the resonant x-ray scattering and provide an extended analysis of transition matrix elements also including electric octupole (E3)

Multiple scattering theory based on a cluster model is used to simulate full-hemispherical X-ray photoelectron diffraction measure- ments in order to verify how state of the art

Actually, the CDW gap is directly measured in this RIXS experiment, since electron-hole excitations between the occupied and unoccupied bands are probed, whereas in the
