| Outline of Final Research Achievements |
In helium-3 nuclear spin polarization by the spin exchange optical pumping (SEOP) method, the low density of Rb used in the process of polarization is one of the factors that limit performance. Therefore, I proposed a new method that uses alkali metal loaded in zeolite in the SEOP method, and I conducted a demonstration experiment. I also proceeded with the development of the polarized 3He neutron spin analyzer which can cover large solid angle detector banks. This polarized 3He neutron spin analyzer has been determined to be installed to a small angle neutron scattering instrument in J-PARC.
