Description
Hadron interaction model for light nucleus has an important roll in understanding neutrino reaction in a large neutrino detector. In Super-Kamiokande, neutral current quasi-elastic interaction (NCQE) induced by atmospheric neutrino gives 68-82% uncertainty on search for diffuse supernova neutrino background, which is caused by the uncertainty on interaction model between oxygen and high energy neutron generated by NCQE interaction.
Therefore, we performed a simulation study by comparing with newly released neutron-oxygen experimental data from E525 experiment. The result of comparison among combinations of intranuclear cascade and de-excitation model are presented in order to choose a model giving better prediction based on the experimental data.
