Abstract

Here, a classic region of band termination at high spin occurs in rare-earth nuclei with around ten valence nucleons above the ¹⁴⁶Gd closed core. The results are presented here for such non-collective oblate (γ = 60°) terminating states in odd-Z ¹⁵⁵Ho, odd-odd ¹⁵⁶Ho, and even-even ¹⁵⁶Er, where they are compared with neighboring nuclei. In addition to these particularly favoured states, the occurrence of collective triaxial strongly deformed (TSD) bands, bypassing the terminating states and extending to over 65ℎ, is reviewed

Shape evolution of neutron-rich ^106,108,110Mo isotopes in the triaxial degree of freedom

Journal Article Ha, J. ; Sumikama, T. ; Browne, F. ; ... - Physical Review C

Background: Neutron-rich nuclei with mass number between 100 and 110 attract much attention, since several kinds of shapes, such as spherical, prolate, oblate, and triaxial shapes, are predicted. In particular, for neutron-rich Mo isotopes, different models predict different magnitudes and rigidity of triaxial deformation. Previous interpretations of experimental results based solely on low-lyingmore »« less

High-spin terminating states in the $N = 88$ ${}^{155}{Ho}$ and ${}^{156}{Er}$ isotones

Journal Article Rees, J. M. ; Paul, E. S. ; Simpson, J. ; ... - Physical Review. C, Nuclear Physics

Here, the ¹²⁴Sn(³⁷Cl,6nγ) fusion-evaporation reaction at a bombarding energy of 180 MeV has been used to significantly extend the excitation level scheme of ¹⁵⁵₆₇Ho₈₈. The collective rotational behavior of this nucleus breaks down above spin I ~ 30 and a fully aligned noncollective (band terminating) state has been identified at I^π = 79/2^–. Comparison with cranked Nilsson–Strutinsky calculations also provides evidence for core-excited noncollective states at I^π = 87/2^– and (89/2+) involving particle-hole excitations across the Z = 64 shell gap. A similar core-excited state in ¹⁵⁶₆₈Er₈₈ at I^π = (46⁺) is also presented.

Structure changes in {sup 160}Er from low to ultrahigh spin

Journal Article Ollier, J ; Simpson, J ; Riley, M A ; ... - Physical Review. C, Nuclear Physics

A spectroscopic investigation of the {gamma} decays from excited states in {sup 160}Er has been performed in order to study the changing structural properties exhibited from low spin up toward ultrahigh spin (I{approx}60({h_bar}/2{pi})). The nucleus {sup 160}Er was populated by the reaction {sup 116}Cd({sup 48}Ca,4n{gamma}) at a beam energy of 215 MeV, and resulting {gamma} decays were studied using the Gammasphere spectrometer. New rotational structures and extensions to existing bands were observed, revealing a diverse range of quasiparticle configurations, which are discussed in terms of the cranked shell model. At spins around 50({h_bar}/2{pi}) there is evidence for oblate states closemore »« less
