Particle identification done using |DE-E 17B 6c technique. Scattered {+17}B projectiles and reaction products detected 17B 7c and identified with a Si telescope after H{-2} target.

Kelley and C.G. Sheu (TUNL), November 17, 2014. 17B c The authors measured the charge changing reaction cross sections of 17B 2c boron isotopes and deduced their root mean square proton radii. 17B c Beams of |? 850 - 900 MeV/nucleon boron isotopes were produced by 17B 2c fragmenting {+22}Ne({+10,14-17}B) and {+40}Ar({+11-13}B) ions on a 17B 3c thick {+9}Be foil at the GSI/FRS fragment separator. The beam species 17B 4c were identified by |DE (ionization chamber) vs time-of-flight before 17B 5c they impinged on a 4.010 g/cm{+2} thick carbon target. An ionization 17B 6c chamber located after the target was used to identify charge changing 17B 7c reaction events. 17B c In the discussion, the rms proton radii for {+10,11}B are obtained from 17B 2c e{+-} and |p{+-} scattering and muonic x-ray studies, while for heavier 17B 3c boron isotopes the proton radii are obtained by analyzing the charge 17B 4c changing cross sections, |s{-|a}, in a Glauber model. Finally, the rms 17B 5c proton radii are compared with rms matter radii derived from 17B 6c interaction cross section measurements in the literature. 17B cL J$From Adopted Levels of {+17}B in ENSDF database. 17B L 0 (3/2-) 17B cL ${Ir}{-rms}(proton)=2.67 fm {I2} obtained from Glauber model analysis 17B 2cL of the charge changing cross section |s{-|a}=759 mb {I4} at 17B 3cL E({+17}B)=862 MeV/nucleon. 17B cL $2014Es07 deduced {Ir}{-rms}(neutron)=3.12 fm {I7} from proton and 17B 2cL matter rms radii, implying a thick neutron surface of 0.45 fm {I8}
