Outline of Final Research Achievements

Proton resonant scattering is one of useful experimental tools in nuclear physics. Recent development of low-energy RI beams (secondary beams of unstable nuclei) allows us to study proton resonant scattering on unstable nuclei. We are aiming at developing a new technique of “spin polarized proton resonant scattering in inverse kinematics” by replacing a conventional proton target for RI beams with a spin-polarized proton target. One of the first possible applications of the new technique is for proton resonant scattering on carbon-9. In this study, we developed recoil proton detectors and a low-energy carbon-9 beam toward the future spin-polarized resonant scattering experiment. We also performed a test measurement of unpolarized proton resonant scattering on carbon-9.
