RCNP E398 16O,12C(p,p’) experiment: Measurement of the γ-ray emission probability from giant resonances in relation to 16O,12C(ν,ν’) reactions

We propose to measure the gamma-ray emission probability from excited states above 5 MeV including giant resonance of O-16 and C-12 as a function of excitation energy in 1-MeV step. Here, we measure both the excitation energy (E-x=5-30MeV) at the forward scattering angles (0 degrees-3 degrees) of the O-16, C-12 (p, p') reaction using Grand-Raiden Spectrometer and the energy of gamma-rays (E,) using an array of NaI(Tl) counters. The purpose of the experiment is to provide the basic and important information not only for the gamma-ray production from primary neutral-current neutrino-oxygen (-carbon) interactions but also for that from the secondary hadronic (neutron-oxygen and -carbon) interactions.
