The interaction cross-sections of neutron-deficient 72,76,80Kr isotopes have been measured by use of the transmission method at relativistic energies. Based on the Glauber model analysis effective root-mean-square matter radii of these nuclei have been determined for the first time. A systematic evolution of the matter radii in the mass A ∼70 region is discussed and compared with that of light nuclei.
