Inspired by the newly discovered experimental data, the nuclear structure of the light superheavy nuclei are studied. The single-particle structure, high-K isomers, rotational properties and α-decay energies of the light superheavy nuclei are investigated within the framework of the cranked shell model (CSM) with pairing correlation treated by a particle-number-conserving (PNC) method....

8. Rotational excitations in rare-earth nuclei: a comparative study within different cranking modelsZhen-Hua Zhang (North China Electric Power University, China)14/07/2023 09:00
High-spin rotational bands in rare-earth Er, Tm and Yb isotopes are investigated by (1) the cranked relativistic Hartree-Bogoliubov approach with Lipkin-Nogami method, (2) the cranking covariant density functional theory with pairing correlations treated by a shell-model-like approach or the so called particle-number conserving (PNC) method, and (3) cranked shell model (CSM) with pairing...

Go to contribution page
Several new bands have been identified in $^{130}$Ba, among which there is one with band-head spin 8$^+$. Its properties are in agreement with the Fermi-aligned νh$^2_{11/2}$, 7/2$^−$[523] ⊗ 9/2$^−$[514] Nilsson configuration. This is the first observation of a two-quasiparticle t-band in the A=130 mass region in experiment. The observed bands are discussed... -

The exotic collective excitation modes called chirality and wobbling have been experimentally investigated in the $^{135,136,137}$Nd and $^{135}$Pr nuclei. Many new bands have been identified which were explored by the constrained tilted axis cranking covariant density functional theory, as well as by newly developed particle-rotor models. A good agreement between experimental data and the...

20. Collectivity and chirality in extremely neutron deficient $^{119}$Cs, $^{119}$Ba, and $^{118}$CsKuankuan Zheng (Institute of Madern Physics, Chinese Academy of Sciences)14/07/2023 11:00
The very neutron-deficient strongly-deformed $^{119}$Cs, $^{119}$Ba, and $^{118}$Cs nuclei have been studied with the JUROGAM 3 + MARA recoil-mass separator setup. Two most complete level schemes from low to high spin in the odd-even and odd-odd proton-rich cesium nuclei, $^{119}$Cs and $^{118}$Cs, were observed. One new rotational band and several low-lying states were newly identified in...

Sinegugu Mthembu (iThemba LABS, National Research Foundation, PO Box 722, Somerset West 7129, South Africa)14/07/2023 11:30
It was recently proposed that odd-mass triaxial nuclei can exhibit wobbling motion at low spins. Exited bands identified as wobbling were reported in several nuclei, including in the two gold isotopes of $^{183,187}$Au. The Au isotopes are good candidates for studying such phenomena as the nuclei in this mass region are strongly affected by the triaxial degree of freedom. An excited band with...

The nuclei in the mass region A ∼ 125 are susceptible to shape changes due to presence of the unique parity h$_{11/2}$ orbital. Owing to the larger angular momentum of this orbital compared to the other subshells near the Fermi surface, it serves an essential role in the building up of angular momentum. It is also responsible for the observation of shape changes as protons occupying h$_{11/2}$...
