The configurational entropy and the chemical potential in the molecular‐field approximation are derived for interstitials in solids applying the following model: The host lattice is divided into cells of such a size that at maximum concentration each cell is occupied by one interstitial. Within each cell the interstitial may occupy n distinguishable positions. For n = 1 the results of the lattice gas model are reproduced whereas n ≫ 1 yields the van der Waals isotherms.
