Abstract:
1. A nuclear spin polarized rare gas production device comprising: a flat-surface flow cell unit which has flat sheet surfaces facing each other via a gap, and allows a mixture gas of rare gas and optically-pumping catalyst to flow in the gap in one direction thereof; a laser beam irradiation unit for applying a laser beam toward at least one of the flat sheet surfaces to apply an excitation light into the flat-surface flow cell unit; and a magnetic field application unit for allowing a magnetic line of force to pass through the laser beam-applied flat sheet surface perpendicularly or almost perpendicularly; wherein an alkali metal of the optically-pumping catalyst is deposited inside the facing flat sheet surface opposite the laser beam-applied flat sheet surface, and wherein the deposition of the alkali metal is formed at a state where a temperature of the alkali metal-deposited flat sheet surface is lower than temperatures of a reservoir of the alkali metal and inside thereof by 5° C. to 200° C. at a state where both the reservoir of the alkali metal and the flat-surface flow cell unit are in a high vacuum of 10
