• The one-electron enersv band structure for UGes, which has attracted interestas a tvrical srin-fluctuation s>zstem, is calculated b"z an APW method with theLSD ar>t>roximation exchanne rotential. Relativistic effects are taken into ac-count. The 5f electrons h>'bridise with the Ge 4P electrons considerablv and formbands which srread over about 0.2 R>'d. The Fermi level lies at a sharr>reak in thedensitv of states. The Fermi surface, the extremal cross-sectional area and thecyclotron mass are calculated carefully. The Fermi surface consists of two closedhole sheets centred at R in the einhth and ninth bands, and a lens-like electronpocket at M and a hollow-ball-like electron sheet centred at R in the tenth bana.There exists no or>en orbit. These calculated results account well for experimentalresults for the de Haas-van Alphen effect and the magnetoresistance.
