Detection of the Static Magnetic Field Produced by the Oriented Nuclei of Optically PumpedHe3Gas

Abstract
A new type of very sensitive low-field magnetometer is used to detect the static magnetic field produced by optically pumped He3 nuclei in a vapor. Various signals (pumping and relaxation transients) are obtained in this way. This magnetostatic detection allows a direct study of He3 nuclear polarization without perturbing the spins.
