Abstract

High-spin yrast structures of even-even superheavy nuclei $^{254-258}$ Rf are investigated by means of total-Routhian-surface approach in three-dimensional ( $\beta_2, \gamma, \beta_4$ ) space. The behavior in the moments of inertia of $^{256}$ Rf 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 $^{254,258}$ Rf.
