Relativistic energy-band structure of Mg2Pb

The energy-band structure of Mg2Pb as calculated by the relativistic orthogonalized-planewave method is described. The valence-band edge is found to be at the zone center and the conduction-band edge at the zone boundary, probably at the point X. Band parameters are calculated and compared with recent Fermi-surface data. © 1970 The American Physical Society.
