Neutron to proton cross section ratios in neutrino and antineutrino charged current reactions for Eν < 30 GeV

Using the freon filled bubble chamber SKAT at the Serpukhov accelerator we study event charge distributions in neutrino and antineutrino charged current reactions in the (anti)neutrino energy region from 3-30 GeV. We derive from the data the total cross section ratios of reactions on neutrons to reactions on protons Rν=2.24±0.18 and R sub(anti ν)=0.43±0.10 in agreement with the predictions of the quark parton model. These values agree also with other experimental results at different energies. For neutrino reactions we study additionally the differential distributions in Bjorken variables x and y. (orig.)
