General Comments:

Measured two-proton removal cross section, σinclusive=1.50 mb 10, from 28Mg (2004Bb03, 2003Ba52 - Same group).

Production cross section |J0.01 mb, measured in 40Ar fragmentation reactions of both 9Be(40Ar,X), E=90A MeV, and 181Ta(40Ar,X), E=94A MeV - 2007No13. In 2006Kh08, cross section=2221 mb 21 at magnetic rigidity (Bρ)=2.753 Tm, E=51.75 MeV/u and cross section=2229 mb 15 at Bρ=2.575 Tm, E=45.25 MeV/u for Si(28Ne,X) and related reduced strong absorption radius <r02|>1.203 fm2 7 are measured. The later one is used to study the isospin dependence of the reduced strong absorption radius. Measured production cross section of 26Ne from 36S fragmentation, E=75 MeV/u, on Ta and C targets are |J0.1 mb/sr and |J0.01 mb/sr, respectively, at θ=0 (1999Dl01).
