We give a semiclassical interpretation of the mass asymmetry in the fission of heavy nuclei. Using only a few classical periodic orbits and a cavity model for the nuclear mean field, we reproduce the onset of left-right asymmetric shapes at the fission isomer minimum and the correct topology of the deformation energy surface of {sup 240}Pu in the region of the outer fission barrier. {copyright} {ital 1997} {ital The American Physical Society}
