Abstract
We present our final results on double-pion production by muon-type neutrinos observed in a 2.4× (365 000) picture exposure of the Argonne 12-foot deuterium- (hydrogen-) filled bubble chamber. The reactions , , and are studied. The data, which shows strong production, has nucleon- mass distribution peaked at low masses in all three reactions. The excitation functions for the three reactions exhibit a rapid rise over the energy range from threshold up to about 3 GeV, but thereafter the energy dependence appears less pronounced. The threshold behavior of the cross sections for these reactions is analyzed in the context of a model developed by Adjei, Dicus, and Teplitz. Data from the constrained reaction, , satisfy the Adler conserved-vector-current test.
