Abstract. Calculations of structural phase transitions В1 - В2 under pressure in
chalcogenides of alkaline-earth metals were carried out on the basis of approach of the
local density functional theory, where as a fitting used was the constructive amendments
of the potential by means of the electronic density received in a self-coordinated
calculation using the approximation of the local density.
Keywords: alkaline-earth metal chalcogenides, local density functional theory.
