Band Structure and Fermi Surface of Gallium by the Pseudopotential Method

The band structure of gallium has been calculated using a local semiempirical pseudopotential without spin-orbit coupling. The Fermi surface consists of six closed electron sheets, one closed hole sheet, and a large multiply-connected hole sheet. The calculated surface explains much of the experimental data and is a good representation of the larger pieces. However, the analysis of the data indicates that one or more very small pieces may have been missed in the calculation. Condon's unpublished de Haas-van Alphen data are included in the Appendix.
