    "abstract": "We give a semiclassical interpretation of the mass asymmetry in the fission\nof heavy nuclei. Using only a few classical periodic orbits and a cavity model\nfor the nuclear mean field, we reproduce the onset of left-right asymmetric\nshapes at the fission isomer minimum and the correct topology of the\ndeformation energy surface in the region of the outer fission barrier. We point\nat the correspondence of the single-particle quantum states responsible for the\nasymmetry with the leading classical orbits, both lying in similar equatorial\nplanes perpendicular to the symmetry axis of the system.",
