RCNP E398 ~(16)O,~(12)C(p,p') Experiment: Measurement of The y-ray Emission Probability from Giant Resonances in Relation To ~(16)O,~(12)C(v,v') Reactions

摘要

We propose to measure the y-ray emission probability from excited states above 5 MeV including giant resonance of ~(16)0 and ~(12)C 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°-3°) of the ~(16)O, ~(12)C (p, p') reaction using Grand-Raiden Spectrometer and the energy of γ-rays (E_γ) using an array of NaI(Tl) counters. The purpose of the experiment is to provide the basic and important information not only for the y-ray production from primary neutral-current neutrino-oxygen (-carbon) interactions but also for that from the secondary hadronic (neutron-oxygen and -carbon) interactions.
