Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0 | 2.8 m 6 % β- = 100 | Only β- decay mode is possible and has possibly been observed by 2003Xu08. E(level): Only β- decay mode is possible and has possibly been observed by 2003Xu08. | |
| X | 78 ns 7 % IT = 100 | Four γ rays with almost equal intensities were reported by 2008StZY at 204, 416, 487 and 629 keV, but the level scheme was not established. |
2003Xu08: 197Os formed in Pt(n,2p) reaction at E(n)=14 MeV and natural Pt target. Measured γ rays in singles and coincidence from decay of 197Os. Ten γ rays were reported to populate levels in 197Ir. Since no mass or chemical separation was attempted in the experiment by 2003Xu08, the evaluator treats the identification and half-life measurement as tentative.
2008St20, 2008StZY: 197Os formed by fragmentation of 208Pb beam at 1 GeV/nucleon from SIS accelerator at GSI facility. Nuclei of interest were separated using FRS. The transmitted ions were slowed in Al degraders and stopped in a plastic catcher. The catcher was surrounded by RISING γ-ray spectrometer to measure γ rays correlated with fragments. Many events were assigned to 197Os in the fragment yield distribution shown by 2008St04
