We have performed cluster calculations in a study of the bonding nature in the CeO 2 crystal using the relativistic discrete-variational X a method. The electron charge distribution of CeO 2 is compared with those of ZrO 2 and CaF 2. The charge density in the metal atomic region indicates stronger c
## Abstract General formulae for the elastic constants of purely and partially covalent cubic crystals are derived. For the mixed covalentβionic bond a new model of electron localeβtransition is proposed, according to which the ionicity of a bond depends on the bonding angle. This model can account
