• The one~lectron energy band structure for LaSn3. which attracts interest as a proper reference material fqr the study of the valence-fluctuating state in CeSn3, is calculated by a self<:onsistent APW method with the local-spin-density approxi-mation exchange potential. The narrow La 4f bands lie a few eV above the Fermi energy, EF, and do not affect the Bloch states near EF Seriously. The partial and total density of states, the Fermi surface, the angular variation of the extremal cross-sectional area and the cyclotron mass are carefully calculated. The Fermi surface consists of a small, nearly spherical hole sheet centred at r in the seventh band. and a small, highly distorted hole sheet centred at r and a large multiply~0nnected sheet in the eighth band. Thcse calculated results account reasonably well for the recent de Haas-van Alphen effect experiment.
