Title: Description of $^{158}$ Er at ultrahigh spin in nuclear density functional theory

Abstract

Rotational bands in 158Er at ultrahigh spin have been studied in the framework of relativistic and nonrelativistic nuclear density-functional theories. Consistent results are obtained across the theoretical models used but some puzzles remain when confronted with experiment. Namely, the many-body configurations which provide good description of experimental transition quadrupole moments and dynamic moments of inertia require substantial increase of the spins of observed bands as compared with experimental estimates, which are still subject to large uncertainties. If, however, the theoretical spin assignments turned out to be correct, experimental band 1 in 158Er would be the highest spin structure ever observed.

Unexpected $5 / 2^{-}$ spin of the ground state in $^{147}$ Ba: No octupole deformation in ground states of odd- $A$ Ba isotopes

Journal Article Rząca-Urban, T. ; Urban, W. ; Smith, A. G. ; ... - Physical Review. C, Nuclear Physics

The ¹⁴⁷Ba nucleus has been studied in prompt γ-ray spectroscopy using the EUROGAM2 Ge array. Spin and parity of the ground state has been determined to be 5/2 ^-. The unexpected, 5/2 ^- ground state results from interaction with other negative-parity configurations. A new ground-state band has been established in ¹⁴⁷Ba and some previously reported levels have been arranged into a 3/2 ^- band, which may correspond to the 3/2 ^-[532] configuration. The new spin assignments in ¹⁴⁷Ba suggest that the theoretical predictions of static octupole deformation in the ground state of ¹⁴⁷Ba may not be be valid. No candidatesmore »« less

Self-Consistent Tilted-Axis-Cranking Study of Triaxial Strongly Deformed Bands in ^{158}Er at Ultrahigh Spin

Journal Article Shi, Yue ; Dobaczewski, J. ; Frauendorf, S. ; ... - Physical Review Letters

Stimulated by recent experimental discoveries, triaxial strongly deformed (TSD) states in ^{158}Er at ultrahigh spins have been studied by means of the Skyrme-Hartree-Fock model and the tilted-axis-cranking method. Restricting the rotational axis to one of the principal axes - as done in previous cranking calculations - two well-defined TSD minima in the total Routhian surface are found for a given configuration: one with positive and another with negative triaxial deformation gamma. By allowing the rotational axis to change direction, the higher-energy minimum is shown to be a saddle point. This resolves the long-standing question of the physical interpretation of themore »« less

Return of Collective Rotation in {sup 157}Er and {sup 158}Er at Ultrahigh Spin

Journal Article Paul, E S ; Twin, P J ; Evans, A O ; ... - Physical Review Letters

A new frontier of discrete-line {gamma}-ray spectroscopy at ultrahigh spin has been opened in the rare-earth nuclei {sup 157,158}Er. Four rotational structures, displaying high moments of inertia, have been identified, which extend up to spin {approx}65({Dirac_h}/2{pi}) and bypass the band-terminating states in these nuclei which occur at {approx}45({Dirac_h}/2{pi}). Cranked Nilsson-Strutinsky calculations suggest that these structures arise from well-deformed triaxial configurations that lie in a valley of favored shell energy which also includes the triaxial strongly deformed bands in {sup 161-167}Lu.
