## Title

- title: Energy redistribution of the valence electrons due to nanodispersion of materials
    and its evidence as determined by the ultrasoft X-ray emission spectra
  title_type: original
  lang: en

## Description

- description: An investigation under equal experimental conditions of the ultrasoft
    x-ray emission bands of coarse-grained and nanosize powders of different materials
    reveals the narrowing of the spectra and changes of their shapes when decreasing
    powder size. As shown, this is a consequence of the energy redistribution of valence-electron
    states after the breaking of interatomic bonds under dispersion of the materials
    into nanosizes, when a number of surface atoms with broken bonds become commensurable
    with the number of atoms within the nanoparticles. The energy redistribution of
    electrons occupying mainly the π-bonding states is changed significantly due to
    the increasing curvature of the surfaces of carbon nanomaterials with the decrease
    of their sizes. As revealed, the specific narrowing of the x-ray emission bands
    representing electron states of some symmetry is proportional to occupancy of
    these states.
