Charged-current single pion production in scattering off? 12C is investigated for neutrino energies up to 1 GeV. An impact of nuclear e?ects with in-medium modi?cations of the ?Deta(1232) resonance properties as well as an e?ffective ?eld theory nonresonant background contribution are discussed. Dependence of the fraction of Delta?(1232) decays into npnh states on incident neutrino energy is estimated. A model of Nieves et al. [1] is further developed by performing exact integration avoiding several approximations. The eff?ect of exact integration is investigated both for double-di?erential and total neutrino-nucleus cross sections.
