Structure of superdeformed bands in the A ≈ 150 mass region

New high-spin level scheme of neutron-rich112Rh

“…More details can be found in Refs. [24]. The present calculations support that the negative-parity yrast and yrare bands of 112 Rh are built on the πg 9/2 ⊗ νh 11/2 configuration, which is consistent (7 ) 60.6 with the previous conclusions based on the stystematics.…”

γ-ray spectroscopy of the odd-oddN=Z+2deformed proton emitter112Cs

“…Figure 5(a) presents the Fig. 5 here calculated quadrupole deformation parameters β 2 for the odd-odd cesium isotopes with 55 ≤ N ≤ 71 (110 ≤ A ≤ 126), taken from the macroscopic-microscopic approach of Möller, Nix, Myers, and Swiatecki [2], from the total-Routhiansurface (TRS) method [34,35], and from a Hartree-Fock-Bogolyubov (HFB) self-consistent mean-field approach [36]. All of these calculations reveal that the cesium isotopes with 112 ≤ A ≤ 126 are expected to have sizable groundstate quadrupole deformations.…”

“…TRS calculations [34,35] were performed for all likely configurations of the valence neutron and proton. The deformations for all of the configurations were found to lie within a small range with 0.186 ≤ β 2 ≤ 0.211, 0.033 ≤ β 4 ≤ 0.044, and −2 • ≤ γ ≤ 12 • .…”

Superdeformed multi-quasiparticle high-Kstates and possible isomers in Pb and Po isotopes

“…Intensity is generally transferred out of the bands before they reach the bandheads. Therefore the information concerning the structure of SD bands was mainly obtained indirectly from the behavior of the dynamic moment of inertia (J (2) ) versus the rotational frequency [3,4]. For even-even nuclei in the A ∼ 190 region, the rise of J (2) of yrast SD bands was attributed to the gradual alignment of pairs of high-j intruder orbitals as predicted in various mean-field plus cranking calculations with explicit pairing [5][6][7].…”
