    "abstract": "We investigate the structure of the potential energy surfaces of the\nsuperheavy nuclei 258Fm, 264Hs, (Z=112,N=166), (Z=114,N=184), and (Z=120,N=172)\nwithin the framework of self-consistent nuclear models, i.e. the\nSkyrme-Hartree-Fock approach and the relativistic mean-field model. We compare\nresults obtained with one representative parametrisation of each model which is\nsuccessful in describing superheavy nuclei. We find systematic changes as\ncompared to the potential energy surfaces of heavy nuclei in the uranium\nregion: there is no sufficiently stable fission isomer any more, the importance\nof triaxial configurations to lower the first barrier fades away, and\nasymmetric fission paths compete down to rather small deformation. Comparing\nthe two models, it turns out that the relativistic mean-field model gives\ngenerally smaller fission barriers.",
