General Comments:

Identification: cross-bombardments, excitation functions, and coincidences with x rays in 36Ar, 40Ar bombardments of Cs, Ba, La and Pr (1987ScZL). See also 1989Me02 (167W produced in 136Ba(36Ar,xn) E=191 MeV).

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

Q-value: ΔQ(β)=340, ΔS(n)=310, ΔS(p)=430 (1995Au04).

Q-value: Q(α)=4671 13 or 4659 20, respectively, from Eα=4559 13 (1991Me05) or 4550 20 (1989Me02), if g.s. to g.s. transition.

E(level): From least-squares adjustment of Eγ, assuming E=79+x keV for the (7/2-) level. The stated uncertainties do not include the uncertainty in E(79+x level) because it is not known.

Jπ(level): From (HI,xnγ), except as noted. Values are based on γ multipolarities deduced from γ(θ) and DCO ratio data, deduced band structure and systematics of known structures in heavier isotopes and isotones. See (24Mg,4nγ) data set for additional details.

E(γ): From 142Nd(30Si,5nγ), except as noted.

I(γ): Relative photon branching from each level; values are from 142Nd(30Si,5nγ), except as noted.

M(γ): From DCO ratio in (30Si,5nγ) and/or γ(θ) in (24Mg,4nγ). Stretched Q intraband transitions are assigned as (E2).
