Q(β-)=3.08×103 keV 10S(n)= 4.89×103 keV 10S(p)= 9.2×103 keV SYQ(α)= 3.E2 keV SY
Reference: 2012WA38

General Comments:

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).

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β)=200, ΔS(n)=200, ΔS(p)=450, ΔQ(α)=450 (2003Au03)

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.
