Study of nuclear effects in the inclusive neutrinoproduction of the δ^{++}(1232) isobar

For the first time, the inclusive neutrinoproduction of Δ^{++}(1232) from nuclei is investigated. The total yield of $Δ^{++}(1232) in neutrino-nuclear interaction is found to be \ < n\ >_{νA} = 0.080\pm0.011, being compatible with \ < n\ >_{νN} = 0.091\pm0.013 inferred for neutrino-nucleon interactions. It is shown that the Δ^{++}(1232) inclusive spectra on variables x_F, z and the isobar total momentum for νA interactions are shifted toward lower values respective to those for νN interactions, that can be caused by secondary intranuclear collision processes. No idication on a significant nuclear absorption of Δ^{++}(1232) leading to its disappearance is found.
