| Research Abstract |
Nuclear resonance fluorescence measurements by using laser Compton scattering gamma rays have been carried out to explore the magnetic dipole (M1) structure in closed-shell nuclei and their neighbors. We have obtained the M1 strength distribution of iron nuclei which is necessary for evaluation of inelastic neutrino reaction rates. Furthermore, we have performed shell model calculations and elucidated that the M1 transitions above the excitation energy of 6 MeV are mainly caused by particle-hole excitation between f5/2 and f7/2 orbitals.
