We report a measurement of the νμcharged current quasielastic cross-sections on carbon in the T2K on-axis neutrino beam. The measured charged current quasielastic cross-sections on carbon at mean neutrino energies of 1.94 GeVand 0.93 GeVare (11.95 ± 0.19(stat)-1.47+1.82(syst)) × 10-39cm2/neutron, and (10.64 ± 0.37(stat)-1.65+2.03(syst)) × 10-39cm2/neutron, respectively. These results agree well with the predictions of neutrino interaction models. In addition, we investigated the effects of the nuclear model and the multi-nucleon interaction.
