AB  - High-energy spectroscopy has been used to study the electronic structure and valence state of new ternary intermetallic CeM2P2 (M=Fe, Co, Ni) compounds which crystallize in the ThCr2Si2 types. The calculations of electron energy bands E(k) and partial DOS for compounds were performed by the semi- relativistic linear muffin-tin orbital method without considerations of spin-orbit interactions. Effective filling numbers of electrons in different bands of components in CeM2P2 (M=Fe, Co, Ni) compounds have been calculated. Analysis of the results of calculations showed that the degree of occupation of spd-valence orbital of components varies and differs considerably from of external electrons in isolated atoms. The occupancy of d-orbital of M in the CeM2P2 compounds was shown to be significantly larger than in an isolated state. The electron configuration of P in compounds can be described as s1.4p2.8. LIII – absorption spectra Ce in the ternary CeM2P2 (M=Fe, Co, Ni) compounds were obtained at 78 K and 300 K using a tube spectrometer equipped with an RKD -01 coordinate detector. The mixed valence state of Ce was obtained in the investigated compounds. Surface morphologies CeM2P2 (M=Fe, Co, Ni) compounds are investigated by scanning tunneling microscopy (NT-MDT). The range scanning was 100 um x 100 um and 2 um x 2 um. The surface topography, distribution of grain diameter and area were obtained. The distribution of grain diameter and area of the CeM2P2 (M=Fe, Co, Ni) compounds is established. The picture of the distribution of the stiffness of the samples (amplitude and phase fluctuations) is obtained.

AB  - High-energy spectroscopy has been used to study the electron structure and valence state of new ternary intermetallic compounds, which crystallize in the CeNiSi2, ThMn12, ThCr2Si2 and HfFe2Si2 types. The calculations of electron energy bands E(k) and partial DOS for compounds were performed by the semi relativistic linear muffin-tin orbital method (LMTO) without considerations of spin-orbit interactions. Effective filling numbers of electrons in different bands of components in R.E.M2X2 (R.E = Sc, Y, Ce, Yb; M= Fe, Co, Ni, Cu, Pd, Rh; X= P, Si) compounds have been calculated. The electron occupation of the d-states of the M atoms has a dominant influence on the degree of their hybridization. Between the experimental and calculated X-ray emission spectra R.E.M2X2 good agreement has been obtained. LIII - absorption spectra Ce and Yb in ternary YbNi4In and Ce(Yb)M4X8 compounds were obtained at 78K and 300K using a tube spectrometer equipped with an RKD-01 co-ordinate detector. The mixed valence state of Ce and Yb was obtained in the YbNiIn4 and Ce(Yb)M4Al8 compounds.
