General Comments:

Identification: 1982En03 observed 167Os as the α daughter of 171Pt; others produced 167Os directly and confirmed the assignment of its α group through cross-bombardments, excitation functions, and α-energy systematics (1977Ca23,1978Ca11,1981Ho10,1982De11).

Levels: All configurations are from 2009Od02

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

Q-value: ΔS(p)=110 (2003Au03,2009AuZZ). Note that Q(β-)=-9424 75 and S(n)=9136 75 in 2009AuZZ are very nearly the same as in 2003Au03.

Q-value: Q(εp)=8100 70 (2003Au03,2009AuZZ)

Q-value: Q(α): g.s. transition assumed, with 50-keV uncertainty added to reflect lack of information concerning daughter state (2003Au03)

E(level): From least-squares fit to Eγ’s. Normalized χ2=4.1 in comparison to critical χ2=3.8. It is possible that some of the uncertainties in Eγ’s are underestimated.

Jπ(level): As proposed by 2009Od02 in 92Mo(78Kr,2pnγ) based on systematics, comparisons with theoretical predictions and angular distributions for selected transitions
