Abstract: The hyperon rms radii in Λ208Pb and neutron star structure have been studied in the framework of the relativistic mean field theory with nucleons,hyperons and mesons. Attention has been paid on the hyperon coupling constants which can not be accurately determined experimentally. A new relation between the hyperon rms radius in hypernucleus and the properties of a neutron star is proposed,i.e.,the larger the hyperon rms radius,the larger the maximum mass and radius of the star. Further accurate measurement of the hyperon rms radius in Λ208Pb will have important implications for the structure of neutron stars.
