Charged-current exclusive pion production in neutrino-deuterium interactions

High-statistics data from two exposures of the BNL 7-foot deuterium bubble chamber to a wide-band-neutrino beam with an average energy of 1.6 GeV were analyzed for exclusive pion production in charged-current neutrino-deuterium interactions. For the single-pion production reactions, the properties of ${\ensuremath{\Delta}}^{++}$ production and decay as well as the final results of an isospin analysis are presented. New results for single-pion and multipion production are also presented.
