“…In addition, using the conventional RDT method, CE can be correlated with the in-beam γ rays emitted at the target position. Rotational band structures above the K π = 8 − isomers in 250 Fm [292] and 252 No [293] were identified using this approach, which provided valuable information about the possible configurations.…”

Abstract.The structure of nuclear isomeric states is reviewed in the context of their role in contemporary nuclear physics research. Emphasis is given to high-spin isomers in heavy nuclei, with A 150. The possibility to exploit isomers to study some of the most exotic nuclei is a recurring theme. In spherical nuclei, the role of octupole collectivity is discussed in detail, while in deformed nuclei the limitations of the K quantum number are addressed. Isomer targets and isomer beams are considered, along with applications related to energy storage, astrophysics, medicine, and experimental advances.

Abstract. The high-K isomeric states in light superheavy nuclei around A = 250 mass region are investigated by the Cranked Shell Model (CSM) with pairing treated by a Particle-Number Conserving (PNC) method. With including the higher-order deformation ε 6 , both of the high−K multi-particle state energies and the rotational bands in 254 No and N = 150 isotone are reproduced well. The isomeric state energies and the microscopic mechanism of kinematic moment of inertia variations versus rotational frequency are discussed. The irregularity of the two-neutron K π = 8 − state band at ω ≈ 0.17 in 252 No is caused by the configuration mixing with the two-proton K π = 8 − band. .

“…In the transfermium mass region, in-beam measurements have been performed for rotational bands up to high spins, such as for 248,250,252 Cf [4,5], 246,250 Fm [6][7][8], 252,254 No [9][10][11][12], and 256 Rf [1]. Theoretically, their rotational behaviors have been investigated by projected shell model [13][14][15], cranking shell model [16][17][18][19], cranking particle-number-conserving method [20][21][22][23], Hartree-Fock-Bogoliubov (HFB) model with the Skyrme force [24,25], and the relativistic Hartree-Bogoliubov approach [26].…”

Motivated by new experimental spectra in transfermium mass region, we have investigated broken-pair high-K multiparticle excited states and their rotational bands for the N = 150 isotones around Z = 100, by using the configuration-constrained pairing-deformation-frequency self-consistent total-Routhian-surface (TRS) model. In order to avoid the spurious phase transition encountered in the Bardeen-Copper-Schrieffer (BCS) pairing, the particle-number-conserving method has been employed for pairing calculations. Pairing correlations are remarkably reduced for the rotations of broken-pair multiparticle states. The present configuration-constrained TRS calculations reproduce reasonably existing experimental data. The abnormal feature in the recently observed K π = 8 − bands of 252 No and 250 Fm would be associated with configuration mixing.
