The band structure of beryllium has been calculated with the APW method using a local exchange-correlation potential. Comparisons between measured spectroscopic properties and quantities derived from the band structure indicate that the energy eigenvalues are correct within 0.5 eV or better in a region of 5 eV around the Fermi level.
