The band structures of Mg 2 Si, Mg 2 Ge, Mg 2 Sn, and of the solid solution Mg 2 (Ge, Sn) are calculated with an “a priori” version of the pseudopotential method. In the computation of the Mg form factors the Heine‐Abarenkov model potential and a Penn‐type dielectric function have been used. Our results settle the disagreement between previous calculations and recent experimental information.
