Electronic structure of beryllium

The electronic energy bands in beryllium have been recalculated. The earlier work of Terrell [1] was found to contain a systematic error in the form of overlapping muffin tins. The new band structures give a density of states with the Fermi surface lying in the hole like portion, consistent with Hall measurements. All existing calculations misplaced the Fermi surface. As a further check on the new bands, the Hall coefficient A_H was calculated. We obtained A_H = (7.6 ± 0.8) × 10^?24 cgs units for the easy axis or c direction, in excellent agreement with the experimental value of A_H = 8.56 × 10²⁴ cgs units.
