General Comments:

Identification: 1984Sc06; excitation functions for 144Sm(27Al,xn) reactions (x=3 to x=5), Eα(Re) systematics, and theoretical half-life predictions (1973Ta30). 1984Sc06 reassign to 166Re the Eα=5330 10, 2.0 s 3, %α≈100 (1978Sc26) and the Eα=5440 3 (1982De11) activity previously attributed to 167Re, and, to 167Re, the Eα=5140 10, 2.9 s 3 (1978Sc26) activity previously attributed to 168Re along with their own observation of 5136 9, 6.1 s 2 α’s. 1992Me10, however, reject 1984Sc06’s assignments to 167Re and reassign to 167Re the 5250 10, 6.6 s 15 activity (attributed in 1984Sc06 to isomeric 168Re), presumably along with the 5279 3 (1982De11) and 5260 10, T1/2=5.5 s 5 (1978Ca11) activities.

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

Q-value: ΔQ(β)=340, ΔS(n)=190, ΔS(p)=130, ΔQ(α)=110 (1995Au04).

Q-value: Q(α)=5409 3 from Eα=5279 3 (1982De11) if g.s. to g.s. α transition

    0.0(9/2-) 5.9 s 3 
% ε ≈ 99
% α ≈ 1
%α: from 1992Me10, assuming the 137γ and 221γ observed following ε decay of this level represent total ε decay intensity. Supported by T1/2=5.7 s 14 (1992Me10) from γ(167W)(t), which suggests that 167Re ε decay occurs predominantly from the 6 s isomer.
E(level): %α: from 1992Me10, assuming the 137γ and 221γ observed following ε decay of this level represent total ε decay intensity. Supported by T1/2=5.7 s 14 (1992Me10) from γ(167W)(t), which suggests that 167Re ε decay occurs predominantly from the 6 s isomer.
  0+X 3.4 s 4 
% α ≈ 100
%α: α decay observed, but no gammas associated with ε+β+ decay could be identified (1992Me10).
E(level): %α: α decay observed, but no gammas associated with ε+β+ decay could be identified (1992Me10).
