Popis: The energy band structures of MgO, LiF, and NaF are calculated by the LMTO method with a set of different atomic spheres radii. It is shown that MgO is distinct from fluorides in that a pure ionic charge distribution is not achieved. Such a behaviour of the electron density is explained by the presence of a potential barier inside the oxygen atomic sphere near its boundary. As a consequence the charge configuration of MgO is suggested to be close to Mg2+O− plus one electron distributed in the interionic region. [Russian Text Ignored]
