| Outline of Final Research Achievements |
By optical pumping of hot vapors, spin angular momentum of the metal atoms can be transferred to condensed matter. We have demonstrated the spin injection optical pumping of solid materials by using cesium atoms. We planned the technique to be applied to lithium and silver atoms because the ion conductivities are significantly large. In this projects, we developed high-temperature vapor cells and studied binary-metal alloys with nuclear magnetic resonance for stable vapor density. We measured diffusion coefficient of lithium atoms in buffer gas, and performed atomic spectroscopy at high temperature. Coherent population trapping enables us to measure the hyperfine splitting frequency of ground-state lithium atoms in several buffer gases. We presents potential atomic magnetometry at high temperatures.
