Abstract: (Elsevier)

Secondary beams of 3 He, 4 He, 6 He, and 8 He were produced through the projectile fragmentation of an 800 MeV/nucleon 11 B primary beam. Interaction cross sections ( σ I ) of all He isotopes of 790 MeV/nucleon on Be, C, and Al targets were measured by a transmission-type experiment. The interaction nuclear radii of He isotopes R I ( He ) = ( σ I π ) 1 2 − R I ( T ) where R I ( T ) is the radius of the target nucleus, have been deduced to be R I ( 3 He ) = 1.59 ± 0.06 fm , R I ( 4 He ) = 1.40 ± 0.05 fm , R I ( 6 He ) = 2.21 ± 0.06 fm , and R I ( 8 He ) = 2.52 ± 0.06 fm .
