Experimental works:

1997Da07: For details see accompanying data set.

1999CaZW, 1998CaZZ: 92Mo(78Kr,p2n), E=360 MeV, GAMMASPHERE-FMA experiments. 167Ir γ rays were identified, but a level scheme has not been published yet

Other experimental works: 1996Pa01, 1981Ho10, superseded by 1997Da07

Theoretical works:

2001Go20: β2=0.00, β4=0.00, S(p)=-0.3 MeV

1997Mo25: S(p)=-0.78 MeV, S(2p)=0.91 MeV, Q(α)=6.53 MeV, T1/2(β)=0.3235 s, T1/2(α)=10.47 ms

1995Mo29: β2=0.116, β4=-0.011, β6=0.002

1995Ab38: β2=0.15, β4=0.00, S(p)=-0.7 MeV

1976Li30: S(p)=-0.88 MeV, Q(α)=6.64 MeV

Levels: All data from 1997Da07

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

Q-value: ΔS(n)=521 (1995Au04)

Q-value: S(p)=-1086 6, including electron screening, proton energy from 1997Da07

Q-value: Q(α)=6507 5 (1997Da07).
