General Comments:

1974Le02 (also 1972Ga27): identification and production of 189Pb in 182W(16O,9N); 181Ta(19F,11N) and 155Gd(40Ar,6n) reactions, measured half-life and %α decay mode. α preliminary report on the production of 189Pb is quoted in 1967Es05 from a priv. comm. in 1966 from α. Siivola, with T1/2≈50 s.

2009Se13, 2007De09: U(p,X) E=1.4 GeV; measured electromagnetic moments, and mean square charge radii using the Resonance Ionization Laser Ion Source (RILIS) at the ISOLDE (CERN) online mass separator. Uranium carbonite was used as the target. Mean Square Charge Radii taken from 2007De09; uncertainty is taken from 2009Se13. 2006Se18 is from the same group

Mass measurement: 2000Ra23 (also 1999Sc46)

Q-value: S(2n)=19000 15, S(2p)=4304 20, Q(εp)=5069 19 (2017Wa10)
