Rotational properties in even-even superheavy 254-258Rf nuclei based on total-Routhian-surface calculations

  • 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 j15/2 neutron rotation-alignment. The competition between the rotationally aligned i13/2 proton and j15/2 neutron may occur to a large extent in 256Rf. High-spin predictions are also made for its neighboring isotopes 254,258Rf, showing that the alignment of the j15/2 neutron pair is more favored than that of the i13/2 proton pair.

Rotational properties in even-even superheavy 254-258Rf nuclei based on total-Routhian-surface calculations

    Corresponding author: WANG Hua-Lei,

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 j15/2 neutron rotation-alignment. The competition between the rotationally aligned i13/2 proton and j15/2 neutron may occur to a large extent in 256Rf. High-spin predictions are also made for its neighboring isotopes 254,258Rf, showing that the alignment of the j15/2 neutron pair is more favored than that of the i13/2 proton pair.
