Reference: 2017WA10

General Comments:

1963Fl07: 189W produced and identified in 192O(n,α), E=14 MeV reaction followed by chemical separation and measurement of β radiation and half-life. Later measurements: 1965Ka07, 1997Ya03, 1997Mi27. 2002Mi40 and 2009Yu11

Q-value: S(2n)=11860 40, S(2p)=17380 300 (syst) (2017Wa10)

Q-value: Other: Q(β-)=2443 41 from measured mass excess(189Re)=-38063 10 (2013Sh30) and mass excess(189W)=-350620 40 (2017Wa10)
