Kopsavilkums

The model of the molecular duster (MC) which has been applied for perfect MgO and CaO crystals is applied now to F⁺ and F centres in these crystals. A method is proposed to estimate the optical transition energies within the SCCC technique. The calculated values of the absorption maxima of the F⁺ and F centres are in reasonable agreement with experimental data. The procedure is also suggested to estimate the location of the defect levels within the forbidden gap of the perfect crystal. For comparison the analogous calculations of the ionic KCI crystal (perfect and with F centre) are given.
