Q(β-)=-2.83×103 keV 3S(n)= 8.64×103 keV 9S(p)= 4.39×103 keV 3Q(α)= 2.09×103 keV 3

  A  199Tl IT decay (28.4 MS)  B  199Pb ε decay (90 M)

General Comments:

Nuclear structure calculations (levels, band structures): 1989Be34, 1980Kr20, 1977Go09, 1977Ta01, 1976De50, 1976Di14, 1975Me11, 1974Ne16, 1971Na04, 1967Co06

Levels: Except for the lowest levels, the shell model is inadequate to describe observed levels. The core-coupling model extends the description. α rotational band based upon the 9/2[505] state has been observed

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

E(level): From least squares adjustment to adopted Eγ’s, assuming Δ(Eγ)=0.2 keV if not stated

Jπ(level): The assignments for the high spin levels are from (α,2nγ) reaction; based on γ(θ), α(K)exp, excitation function; see 1970Ne06 for detailed discussion.

E(γ): From 199Pb ε decay (90 min) and from (α,2nγ) for gammas from high spin levels above the 749.7-keV isomeric state.

I(γ): 199Pb ε (90 min) and (α,2nγ)
