Interaction cross sections (σI) for all known Li isotopes (Li6-Li11) and Be7, Be9, and Be10 on targets Be, C, and Al have been measured at 790 MeV/nucleon. Root mean square radii of these isotopes as well as He isotopes have been deduced from the σI by a Glauber-type calculation. Appreciable differences of radii among isobars (He6-Li6, He8-Li8, and Li9-Be9) have been observed for the first time. The nucleus Li11 showed a remarkably large radius suggesting a large deformation or a long tail in the matter distribution.
