We plan to measure the branching ratios of \gamma-ray emission (E_\gamma >5 MeV) from giant resonance of ^16O and ^12C, as the functions of excitation energy (E_x). This measurement will provide the fundamental 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. The understanding of the \gamma-ray production will introduce a new neutrino detection method to Supernova neutrino physics and Neutrino oscillation physics. In the second stage, we would like to perform O,C(He,t) (T=1) experiment at 0 degrees to continue the systematic study of spin-isospin response through the measurement of the \gamma-ray production with oxygen and carbon nuclei.
