Abstract

The near-yrast states of ₄₂¹⁰¹Mo₅₉ and ₄₄^103,4Ru_59,60 have been studied following their population via heavy-ion multinucleon transfer reactions between a 136 Xe beam and a thin, self-supporting ¹⁰⁰Mo target. The ground state sequence in ¹⁰⁴Ru can be understood as demonstrating a simple evolution from a quasi-vibrational structure at lower spins to statically deformed, quasi-rotational excitation involving the population of a pair of low-Ω h_11/2 neutron orbitals. The effect of the decoupled h_11/2 orbital on this vibration-to-rotational evolution is demonstrated by an extension of the "E-GOS" prescription to include odd-A nuclei. The experimental results are also compared with self-consistent Total Routhian Surface calculations which also highlight the polarising role of the highly aligned neutron h_11/2 orbital in these nuclei.

Theoretical study of triaxial shapes of neutron-rich Mo and Ru nuclei

Journal Article Zhang, C. L. ; Bhat, G. H. ; Nazarewicz, W. ; ... - Physical Review C, Nuclear Physics

Here, whether atomic nuclei can possess triaxial shapes at their ground states is still a subject of ongoing debate. According to theory, good prospects for low-spin triaxiality are in the neutron-rich Mo-Ru region. Recently, transition quadrupole moments in rotational bands of even-mass neutron-rich isotopes of molybdenum and ruthenium nuclei have been measured. The new data have provided a challenge for theoretical descriptions invoking stable triaxial deformations. The purpose of this study is to understand experimental data on rotational bands in the neutron-rich Mo-Ru region, we carried out theoretical analysis of moments of inertia, shapes, and transition quadrupole moments of neutron-richmore »« less

Evidence for possible shape transitions in neutron-rich Ru isotopes: Spectroscopy of {sup 109,110,111,112}Ru

Journal Article Wu, C Y ; Hua, H ; Cline, D ; ... - Physical Review. C, Nuclear Physics

The spectroscopy of neutron-rich {sup 109,110,111,112}Ru nuclei was studied by measuring the prompt {gamma} rays that originate from fission fragments, produced by the {sup 238}U({alpha},f) fusion-fission reaction, in coincidence with the detection of both fragments. For {sup 109,111}Ru, both the negative-parity (h{sub 11/2} orbitals) and K=5/2 positive-parity (mainly g{sub 7/2} and d{sub 5/2} orbitals) bands were extended to substantially higher spin and excitation energy than known previously. The ground-state and {gamma}-vibrational bands of {sup 110,112}Ru also were extended to higher spin, allowing observation of the second band crossing at the rotational frequency of {approx_equal}450 keV in {sup 112}Ru, which ismore »« less

Decay of a {pi}h{sub 11/2} x {nu}h{sub 11/2} microsecond isomer in {sub 61}{sup 136}Pm{sub 75}

Journal Article Rigby, S V ; Cullen, D M ; Mason, P J. R. ; ... - Physical Review. C, Nuclear Physics

An experiment has been performed to populate several extremely neutron-deficient nuclei around the mass-140 region of the nuclear chart, using a beam of {sup 54}Fe on a {sup 92}Mo target at an energy of 315 MeV. Analysis of these data using recoil-isomer tagging has established that the yrast {pi}h{sub 11/2} x {nu}h{sub 11/2},J{sup {pi}}=(8{sup +}), bandhead state in {sup 136}Pm is isomeric with a half-life of 1.5(1) {mu}s. This isomeric state decays via a 43-keV, probable-E1 transition to a J{sup {pi}}=(7{sup -}) state. Consideration of the theoretical Nilsson orbitals near the Fermi surface suggests that the J{sup {pi}}=(8{sup +}) statemore »« less

The spectroscopy of sup 164 Yb and the loss of collectivity at high spins in even-even ytterbium isotopes

Miscellaneous Xie, Hong

High spin states in {sup 164}Yb were populated via {sup 124}Sn({sup 44}Ca,4n){sup 164}Yb reaction at the 25 MV Tandem Accelerator at the Holifield Heavy Ion Research Facility. Three new transitions were added to the previously known decay sequences of {sup 164}Yb. The extracted B(E1, I {yields} I {minus} 1)/B(E2, I {yields} I {minus}2) ratios for {sup 164}Yb show an enhancement compared to its neighboring isotopes, which suggests that {sup 164}Yb neutron number N = 94 possess an instability with respect to the octupole degree of freedom.

Yrast structures in the neutron-rich isotopes {sup 59,60}Fe and the role of the g{sub 9/2} orbital

Journal Article Deacon, A N ; Freeman, S J ; Smith, J F ; ... - Physical Review. C, Nuclear Physics

The structure of the neutron-rich isotopes {sup 59,60}Fe has been studied with the Gammasphere detector array using fusion-evaporation reactions. Level schemes for these nuclei are presented which have been extended to spins of {approx}20({Dirac_h}/2{pi}). Both isotopes exhibit regular, near-yrast {gamma}-decay sequences which are generated by the intrusion of the g{sub 9/2} orbital into the fp shell-model space. Lower-spin, natural-parity levels are discussed within the context of shell-model calculations using the GXPF1A interaction in the full fp model space. Experimental features of the high-spin bands are compared with total Routhian surface calculations.
