General Comments:

189Re activity was produced and identified by 1963Cr06 in 186W(α,p) and in Os(n,p), E=14 MeV; and by 1963Fl07 in 192Os(d,nα), E=28 MeV. Measured β and γ activities and half-life of 189Re activity. Later studies of 189Re decay: 1965Bl06, 1973Ho27 and 1979Sa18.

An activity with T1/2=4.3 d 5 was assigned to 189Re (1969MuZP) in double-neutron capture in 187Re, and followed with β and γ measurements. But no other reports are published about this activity

An activity of 140 d 20 (1965Bl06, also ≈120 d in 1962Bl12) assigned to 189Re was reassigned to 169-d activity of 184Re isomer by 1973Ho27

Other reports of long half-lives of ≈150 d or >5 y (1951Li19) and ≈300 d (1951Tu09) have never been confirmed (2012Ro36 compilation)

Levels: Band assignments are from 1977Hi06 and 2016Re02

Q-value: S(2n)=12905 8, S(2p)=15660 60 (2017Wa10)

Q-value: Other: Q(β-)=924 10 for measured mass excess(189Re)=-38063 10 (2013Sh30) and mass excess(189Os)=-38986.7 7 (2017Wa10)

Jπ(level): From 190Os(pol t,α) experimental analyzing power and angular distributions fit with DWBA for low-spin (J|<9/2) states. For high-spin (J>9/2) states, the assignments are based on multipolarities of γ transitions from γγ(θ) and conversion coefficients deduced from intensity balance arguments, and band structures (2016Re02).

The β- measurement by 2009Yu11 could not confirm this γ transition with more reliable coincidence measurements. In 190Os(t,α) it is stated that this is level is an unresolved doublet, so this may be a combination of the 471- and 490-keV levels established in β- decay.
