160.1+X | X | E(γ): x |<50 keV; see comment on level energy. M(γ): possibly E1 (2005Ca02). I(x, 192Re) too low for transition to be M2 (2011St21). |
267 | 267 | E(γ): from level-energy difference; γ to g.s. reported in 192Re IT decay (61 s), but Eγ unstated by authors. |
Identification: excitation functions for neutrons on 192Os, observation of known 192Os transitions in (n,p) product (1979KaYT). Also produced in fragmentation of 1 GeV/nucleon 208Pb by a 9Be target (2012Al05, 2011St21, 2008StZY, 2005Ca02, 2001Ca13) and fragmentation of 950 MeV/nucleon 197Au by a Be target (1999Be63).
Levels: The presence of a long-lived, low-energy isomer could arise from a spin trap resulting from the proximity of states formed from parallel and antiparallel coupling of high |W orbitals. Calculations indicate a possible Kπ=8+ ν11/2[615]+π5/2[402] g.s. with a Kπ=3+ ν11/2[615]-π5/2[402] state near 250 keV; alternatively, the g.s. could be Kπ=2- ν9/2[505]-π5/2[402] with various high-J states nearby arising from coupling a 9/2[505], 3/2[512] or 11/2[615] proton with a 5/2[402] or 9/2[514] neutron (2012ReZZ). Another possibility is the coexistence of oblate and prolate shapes; total Routhian surface calculations predict a γ-soft prolate-centered g.s. with a possible oblate state nearby created by the addition of a small amount of collective angular momentum (2012ReZZ).
Levels: For cranked Woods-Saxon-Stutinsky calculation of shape of Re, see 2006Wa31; oblate rotation predicted to coexist with high-K prolate rotation in 192Re.
