Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0.0 | 3.5 m 6 % β- = 100 | Analogy with n=113 isotones for higher mass numbers suggests Jπ=3/2-. Population of 164.5-keV (Jπ=9/2+) level in 185Ta suggests a higher spin for 185Hf. E(level): Analogy with n=113 isotones for higher mass numbers suggests Jπ=3/2-. Population of 164.5-keV (Jπ=9/2+) level in 185Ta suggests a higher spin for 185Hf. |
Activity produced in 186W(n,2p), E(n)=14 MeV, using a 99.85% enriched target. 185Hf was identified by chemical separation and by detection of known γ rays from the β- decay of the daughter nucleus 185Ta. Measured Eγ, Iγ. Detector: HpGe (1993Yu01,1993Zh07).
