| Research Abstract |
Optical pumping of cesium atoms enables to transport the spin angular momentum in the electron spin and the nuclear spin of the atoms. When the spin currents reach to a cesium salt, the spin polarization of atoms is transferred to salt nuclei at the surface. As the result, cesium nuclei are highly polarized in the salt. Studying and optimizing each process such as spin current in the vapor, spin transfer at the surface, and spin diffusion in the salt, we succeeded in the enhancement of Cs NMR signal three-orders of magnitude larger than thermal equilibrium.
