For the first time, the total yield and inclusive spectra of the Δ++(1232)isobar are measured in νp and νn charged-current interactions. An indication is obtained that the Δ++(1232) production mainly results from the neutrino scattering on the valence d- quark of the target nucleon. The total yield of Δ++(1232) in νp interactions is compatible with that measured in hadronic interactions of the same net charge and net baryonic number. The yield of Δ++(1232) in νn interactions is significantly suppressed as compared to the case of the proton target. The form of the squared transverse momentum distributions, both in νp and νn interactions, is found to be compatible with the available data on the neutrinoproduction of Λ hyperon. The experimental data are compared with the LEPTO6.5 model predictions.
