Abstract:

Pairing properties of even-even superheavy $N$=184 isotones are studied within the Skyrme-Hartree-Fock+BCS approach. In the particle-hole channel we take the Skyrme energy density functional SLy4, while in the particle-particle channel we employ the seniority pairing force and zero-range $\delta$-interactions with different forms of density dependence. We conclude that the calculated static fission trajectories weakly depend on the specific form of the $\delta$-pairing interaction. We also investigate the impact of triaxiality on the inner fission barrier and find a rather strong $Z$ dependence of the effect.
