Abstract

Self-consistent Skyrme-Hartree-Fock (SHF) calculations of static fission barriers are presented for even-even Fermium isotopes as well as for superheavy even-even $N$=184 isotones. In the particle-hole channel, we use the SLy4 Skyrme parametrization, while in the particle-particle channel we take a $T$=1 seniority pairing force treated in the BCS approximation. The influence of reflection-asymmetric and triaxial degrees of freedom on the static fission paths are investigated.
