摘要

A systematic search for axial octupole deformation in the actinides and superheavy nuclei with proton numbers Z = 88–126 and neutron numbers from the two-proton drip line up to N = 210 was performed in covariant density functional theory (DFT) using four state-of-the-art covariant energy density functionals representing different model classes. The nuclei in the Z ~ 96, N ~ 196 region of octupole deformation were investigated in detail and the systematic uncertainties in the description of their observables were quantified. A similar region of octupole deformation exists also in Skyrme DFT and microscopic+macroscopic approaches but it is centered at somewhat different particle numbers. Theoretical uncertainties in the predictions of the regions of octupole deformation increase on going to superheavy nuclei with Z ~ 120, N ~ 190. There are no octupole deformed nuclei for Z = 112–126 in covariant DFT calculations. This agrees with Skyrme DFT calculations, but disagrees with Gogny DFT and microscopic+macroscopic calculations which predict an extended Z ~ 120, N ~ 190 region of octupole deformation.
