| Outline of Final Research Achievements |
It is important to suppress spin relaxation on the walls for precise measurements using alkali-metal vapor. For development of anti-spin-relaxation coating on glass walls, we investigated the mechanism of surface relaxation of electron and nuclear spins by means of the following experimental methods: NMR measurement of composition in alkali-metal binary alloys, optical measurement of vapor density on alkali-metal alloys, optical pumping in random scattering media at high magnetic field, spin polarized ion doping in glass materials, spin polarization transfer on the glass walls, vacuum-ultra-violet Faraday rotation by diamagnetic xenon gas, and diffusion spin current by pumped lithium atoms.
