The equilibrial values of the vacancy concentration of chalcogen and antistructural samarium atoms in metallic phase of SmS were calculated by minimization the crystal thermodynamic potential. It was determined that the dominant defects are at the concentration of samarium 50,5-54 at. % and at the temperature of T=300-400 K. Also the concentration of negatively charged sulfur vacancies is less on 1-2 points. The concentric dependence of samarium monosulphide density was explained using this offered model.
