General Comments:

227Rn evaluated by B. Singh.

1986Bo35 (also 1989Bo11): the activity was produced by spallation of 600-MeV protons on targets of 232Th. Assignment to 227Rn was based on mass separation using ISOLDE mass separator, and on the genetic relationship with its daughter nucleus 227Fr. Measured β- and half-life using plastic scintillator detector

1997Ku20 (also 1989Bo11, 1986Bo35): the activity was produced by spallation of 1-GeV protons on targets of 232Th, and subsequently mass separated in the ISOLDE mass separator; measured half-life, Eγ, Iγ, γγ

Precise mass measurements: 2012Ch19, 2009Ne03

Q-value: Estimated uncertainties (2012Wa38): 300 for S(p), 200 for Q(α)

Q-value: S(2n)=9791 18, S(2p)=16220 300 (syst) (2012Wa38)
