We have calculated the Ni 3p x-ray photoemission spectrum (XPS) in ${\mathrm{NiCl}}_{2}$, taking into account the lifetime of Ni 3p hole states due to the ${\mathit{M}}_{2,3}$${\mathit{M}}_{4,5}$${\mathit{M}}_{4,5}$ super-Coster-Kronig decay process.

We investigated theoretically the Cu 2 p resonance of 3 d , 3 p and 3 s X-ray photoemission spectra (XPS) in CuO using a cluster model including multiplet coupling, crystal field and anisotropic hybridization. The spectra were calculated by taking in

The observed enhancement in the 3d, 3p, and 3s photoemission structures at resonance with the 2p absorption edge of nickel is analyzed using a cluster calculation including multiplet structure. The result strongly supports the view of a localized ele

The role of the Cu 4 s conduction band in the Cu 2 p -XPS (X-ray photoemission spectrum) of Nd 2- x Ce x CuO 4 is investigated on the basis of both a simple CuO 4 cluster model and the impurity Anderson model. The impurity Anderson model consists of

A new optical absorption band was found at the peak energy of 17 kcm -1 (590 nm) besides the Cl 2 - band (22.5 kcm -1 =445 nm) in (C n H 2 n +1 NH 3 ) 2 MnCl 4 ( n =1, 2, 3) irradiated with X-rays at 15 K. The absorption intensity of the new band inc

We analyze the polarization dependence of the Cu 2 p -XAS and the Cu 2 p -XPS observed in the YBa 2 Cu 3 O 7-δ system. To take into account the nonequivalent Cu sites in YBa 2 Cu 3 O 7 , we use a model where the impurity Anderson model and a CuO 4 c

We theoretically analyze the spectra of X-ray photoemission, X-ray emission and X-ray adsorption associated with the Cu 2p core level in high-Tc superconducting materials. We use the single-site impurity Anderson model with five Cu 3d orbitals and O

We theoretically study the polarization dependence of the Cu 2 p -XAS (X-ray absorption spectrum) in high T c superconductors with the use of a simple CuO 4 cluster. We take account of both the Cu 3 d ( x 2 - y 2 ) and 3 d (3 z 2 - r 2 ) orbitals, an

We predict very strong peak enhancements in core-level photoemission at the resonance with a deeper core-level absorption. This allows a straightforward interpretation of core-level spectroscopy in two ways: (a) photoemission peaks can be resolved in
