General Comments:

1984Sc06: identification in 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.

     0.0(1/2+) 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). The 3.4-s activity in 167Re is assigned as the ground state with Jπ=(1/2+), and the 5.9-s activity with Jπ=(9/2-); the Jπ assignment based on systematics: 1/2+ g.s. and 11/2- isomer in 161,163,165Re. The energy ordering of the two activities is guided by Eα=5015 keV 12 from the decay of the 3.4-s activity and Eα=5263 keV 12 from the 5.9-s activity. Note that 1992Me10 and 1992Sc16 assigned the 5.9-s activity as the g.s., considering this analogous to 169Re g.s. However, 1992Me10 point out that for small deformations, the 75th proton is expected to occupy the π9/2[514] orbital but, with increasing deformation, the π1/2[411] and then the π5/2[402] orbital crosses the 9/2[514] orbital. Note that the decays of the two activities of 167Re by α decay to 163Ta in the ENSDF database (April 2010 update) are assigned as follows: 3.4 s 4 activity to (9/2-) ground state, and 5.9 s 3 activity to (1/2+) isomer at ≈130 keV, with energy of the isomer taken from systematic trend. The same ordering and arrangement is given in 2021Ko07.
Jπ(level): The 3.4-s activity in 167Re is assigned as the ground state with Jπ=(1/2+), and the 5.9-s activity with Jπ=(9/2-); the Jπ assignment based on systematics: 1/2+ g.s. and 11/2- isomer in 161,163,165Re. The energy ordering of the two activities is guided by Eα=5015 keV 12 from the decay of the 3.4-s activity and Eα=5263 keV 12 from the 5.9-s activity. Note that 1992Me10 and 1992Sc16 assigned the 5.9-s activity as the g.s., considering this analogous to 169Re g.s.

% 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 5.9-s activity.
E(level): Ap |) ApAB. The 3.4-s activity in 167Re is assigned as the ground state with Jπ=(1/2+), and the 5.9-s activity with Jπ=(9/2-); the Jπ assignment based on systematics: 1/2+ g.s. and 11/2- isomer in 161,163,165Re. The energy ordering of the two activities is guided by Eα=5015 keV 12 from the decay of the 3.4-s activity and Eα=5263 keV 12 from the 5.9-s activity. Note that 1992Me10 and 1992Sc16 assigned the 5.9-s activity as the g.s., considering this analogous to 169Re g.s. However, 1992Me10 point out that for small deformations, the 75th proton is expected to occupy the π9/2[514] orbital but, with increasing deformation, the π1/2[411] and then the π5/2[402] orbital crosses the 9/2[514] orbital. Note that the decays of the two activities of 167Re by α decay to 163Ta in the ENSDF database (April 2010 update) are assigned as follows: 3.4 s 4 activity to (9/2-) ground state, and 5.9 s 3 activity to (1/2+) isomer at ≈130 keV, with energy of the isomer taken from systematic trend. The same ordering and arrangement is given in 2021Ko07.
