Very long nuclear relaxation times of spin polarized helium 3 in metal coated cells

1995

Abstract We obtained very long relaxation times T 1 of up to 120 h for the nuclear polarization of an optically pumped helium 3 gas. The glass containers were internally coated with metallic films such as bismuth or cesium. These findings will have applications in the field of helium magnetometers and polarized targets.
