All data are from the study reported by 2010Bi03. The evaluator has assumed that this is a subsequent version of the information presented in 2008PaZV, which has most of the same authors.
161Os produced via the 106Cd(58Ni,3n) reaction, with values of E(58Ni)=290, 300 and 310 MeV. Enriched (96.5%) self-supporting target of thickness 1.1 mg/cm2. Reaction products were separated in-flight in a gas-filled separator and implanted into double-sided silicon-strip detectors. Measured T1/2, Eα and generic relations among members of the decay chain.
2010Bi03 report α peaks having energies of 6890 12 and 6580 30, with the latter having a branching ratio=5.5 31-22%. These authors assign these as transitions to the 157W g.s. and an excited state at 318 30, respectively. With this identification, Q(α)=7066 12 is implied.
Q-value: Note: Current evaluation has used the following Q record 7066 12
