摘　　要：The quenching factors of one-neutron spectroscopic factors,which are ratios of theoretical to experimental one-neutron removal cross sections,are studied for the carbon isotopes ^（15-19）C,with ^（12）C and ~9Be targets within incident energies from around 50 to 900 MeV/nucleon.The resulting values of quenching factors do not show strong energy dependence within such an energy range.The average values of the these quenching factors agree well with the systematics in [J.A.Tostevin and A.Gade,Phys.Rev.C,90 057602（2014）],which was established for a large set of radioactive nuclei with different masses below 305 MeV/nucleon.The quenching factors of one-neutron spectroscopic factors,which are ratios of theoretical to experimental one-neutron removal cross sections,are studied for the carbon isotopes ^（15-19）C,with ^（12）C and ~9Be targets within incident energies from around 50 to 900 MeV/nucleon.The resulting values of quenching factors do not show strong energy dependence within such an energy range.The average values of the these quenching factors agree well with the systematics in [J.A.Tostevin and A.Gade,Phys.Rev.C,90 057602（2014）],which was established for a large set of radioactive nuclei with different masses below 305 MeV/nucleon.
