Abstract

High-spin yrast structures of even-even superheavy nuclei ^254-258Rf are investigated by means of total-Routhian-surface approach in three-dimensional (β₂, γ, β₄) space. The behavior in the moments of inertia of ²⁵⁶Rf is well reproduced by our calculations, which is attributed to the j_15/2 neutron rotation-alignment. The competition between rotationally aligned i_13/2 proton and j_15/2 neutron is discussed. High-spin predictions are also made for its neighboring isotopes ^254,258Rf.
