General Comments:

Some recent nuclear structure calculations: 2006Ko02, 2004La24, 2004Mi31, 2002Ka73, 2002St29.

Atomic mass excess measurement: 24630 keV 190 (2007Ju03)

Measured 27F production cross-sections: σf=2.1 nb 7 from 40Ar fragmentation, E=1.06 GeV/u, on Be target (2000Oz01).

38.97 MeV/u and 34.00 MeV/u beams of 27F on a Si target, measured σ=2096 (164) mb and σ=2468 (256) mb, respectively, for the Si(27F,x) reaction (2006Kh08). α squared reduced absorption radius of r02=1.16 (7) fm2 is deduced and used to study the isospin dependence.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔS(p)=241 (syst); ΔQ(α)=353 (syst) (2011AuZZ)

Q-value: Q(β-)=17900 400, S(n)=1400 400, S(p)=18100 500(syst), Q(α)=-15900 500(syst) 2003Au03
