Abstract

The superheavy nucleus 256Rf, where rotational band and multi-quasiparticle isomer have been observed recently, has been investigated using total Routhian surface calculations and configuration-constrained calculations of potential energy surface, with the inclusion of β 6 deformation. The experimental moment of inertial is well reproduced, indicating that the alignment is delayed due to the β 6 deformation. A K π = 5− or 8− state could form a two-quasiparticle isomer that is calculated to have higher fission barrier than the ground state.
