Opis:: The reflectivity and X-ray absorption near-edge structure spectra for CdTe were calculated with the inclusion of the transition matrix elements from band structure obtained within self-consistent, relativistic linear muffin tin orbital method. The results were compared with experimental data for the case of CdTe and with our previous calculations.

Opis:: The reflectivity and X-ray absorption near-edge spectra (XANES) for CdTe have been calculated with inclusion of the transition matrix element from band structure obtained from self-consistent linear muffin-tin-orbital (LMTO) method. The result has been compared with experimental data for the case of CdTe.

Opis:: The theoretical band structure of the CdTe was calculated using conventional, ab initio, self-consistent, relativistic LMTO method. The projected density of states and the dielectric function were produced within the local density approximation. Spin-orbit coupling was included in the perturbation approach. X-ray absorption spectra for the Cd L$\text{}_{1,3}$- and Te L$\text{}_{1,3}$-edges were calculated and the results compared with experimental data. The teoretical results were obtained from the calculations with inclusion of k-dependent transition matrix elements, spin-orbit coupling, extended set of basis functions and finite lifetime of initial and final states. They were compared with other calculations which use common constant matrix element approximation. The work presents final conclusion concerning validity of using constant matrix element approximation within one-electron scheme.

Opis:: X-ray absorption near-edge structure for Hg$\text{}_{1-x}$Mn$\text{}_{x}$Se and Hg$\text{}_{1-x}$Fe$\text{}_{x}$Se was studied with the use of synchrotron radiation. The self-consistent, semirelativistic LMTO method within the LD approximation was used to calculate electronic band structure and K-edge spectra of these semimagnetic semiconductors. The theoretical results for X-ray absorption spectra were compared with experimental data.
