Description

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 δ-interactions with different forms of density dependence. We conclude that the calculated static fission trajectories weakly depend on the specific form of the δ-pairing interaction. We also investigate the impact of triaxiality on the inner fission barrier and find a rather strong Z dependence of the effect. (author)
