The interaction cross-sections (σI) of neutron-rich Na isotopes, 23-35Na, on C target have been measured at 250A MeV using the RI beam factory (RIBF) at RIKEN. Mass dependence of αI for 27-35Na suggests monotonic growth of the skin thickness. The root-mean-square nuclear matter radii (r̃m) of 23-35Na were deduced from observed σI via a Glauber-type calculation. These r̃ m are in a good agreement with the theoretical prediction by relativistic mean field model (RMF). r̃m of 33-35Na were determined for the first time.
