Abstract

A new type of very sensitive low-field magnetometer is used to detect the static magnetic field produced by optically pumped ${}^{3}{He}$ nuclei in a vapor. Various signals (pumping and relaxation transients) are obtained in this way. This magnetostatic detection allows a direct study of ${}^{3}{He}$ nuclear polarization without perturbing the spins.
