High spin states in {sup 154}Dy were populated via the {sup 36}S({sup 122}Sn, 4n) reaction with a 165-MeV beam provided by the 88' cyclotron at LBNL. The target consisted of a stack of three 0.33 mg/cm{sup 2} self-supporting foils. The decay {gamma} rays were detected with Gammasphere spectrometer array, which consisted of 103 Compton-suppressed germanium detectors at the time of the experiment. A total of 1.5 x 10{sup 9} events was collected, with a requirement of {>=} 5 suppressed Ge detectors in prompt coincidence. Previously known bands were extended to higher spins, up to 51hbar, and at least 4 new bands were found, including a pair of strongly coupled high-K bands. Several bands maintain a smooth rotational behavior up to the highest spins observed. Sharp band terminations were observed at high spins with positive and negative parities, in excellent agreement with theoretical calculations based on the configuration-dependent cranked Nilsson-Strutinsky approach.

New isotope $sup 193$Pb and the structure of $sup 193$Tl shape coexistence in $sup 188$Hg and in $sup 189$Au and a new ion source: recent UNISOR research

J. H. Hamilton K.R. Baker C. R. Bingham

At the 1974 Nuclear Structure Conference, the initial research of UNISOR was described. Brief reports of several UNISOR projects were submitted to the International Conference on Reactions Between Complex Nuclei including studies of cross sections and decays of /sup 186 -190/Tl. UNISOR research was also described in one invited paper. Since that conference there has been a significant breakthrough in ion source development at UNISOR. This has made possible considerably more detailed studies than in previous work. The new ion source is briefly described and some of the recent detailed investigations.

Identification of 181Hg and shape coexistence in odd-A Hg isotopes

Physics Letters B (1997)

P. G. Varmette D.T. Shidot Wenchao Ma A. V. Ramayya R. V. F. Janssens

In-beam γ-ray transitions in 181Hg, the lightest odd-A Hg isotope known thus far, have been identified from fragment mass-γ and γ-γ coincidence measurements. Five prolate deformed rotational bands were placed in the level scheme. A decoupled band built on the strongly prolate deformed 12−[521] ground state was observed up to 292−. A 52−[512] configuration is suggested for a pair of strongly coupled bands displaying no signature splitting. The other two bands are also signature partner bands. They are populated with the largest intensity and exhibit splitting. They have been associated with the mixed neutron i132 orbitals and are proposed to decay to an i132 isomeric state associated with an oblate state.

Shape coexistence inHg190

Physical Review C (1991)

M. Kortelahti E. F. Zganjar John L. Wood C. R. Bingham H.K. Carter

Levels in $^{190}\mathrm{Hg}$ were studied by radioactive decay of isotopically separated $^{190}\mathrm{Tl}$. A new band was observed with spin parity (energy, keV) of ${0}^{+}$(1279), ${2}^{+}$(1571), ${4}^{+}$(1975), and ${6}^{+}$(2510). Electric monopole transitions were observed between this band and the ground-state band. Relative B(E2) values for intraband transitions in the new band were found to be \ensuremath{\sim}200 times those for interband transitions. Systematics of shape coexistence in the light Hg isotopes and their possible relevance to recent observations of superdeformation in these nuclei are discussed.
