Laser Compton Scattering Gamma-Ray Experiments for Supernova Neutrino Process

抄録

The neutrino-nucleus interactions are important for understanding nucleosyntheses by neutrino-induced reactions as well as supernova explosion mechanisms. The M1 strength in atomic nuclei is important for estimation of neutrino-nucleus interactions. We have proposed a method using (γ, n) reactions with linear polarized laser Compton scattering (LCS) γ-rays to measure the M1 strength and verified a theoretical prediction for the first time. We have discussed experimental technique using the next generation of LCS beams.
