Abstract: (APS)

The interaction cross sections (σI) of ANa isotopes (A=20–23,25–32) on a carbon target have been measured at 950AMeV. The effective root-mean-square matter radii of these isotopes were deduced from σI by a Glauber-type calculation. By combining the isotope-shift data with the present data the radii of neutrons have been compared with those of protons for the first time along a chain of stable and unstable isotopes. A monotonic increase in the neutron skin thickness has been observed as the neutron number increases in Na isotopes.
