摘要：

The relaxation time T-1 of He-3 gas, nuclearly polarized by optical pumping, has been significantly increased by internally coating the glass cells with cesium. Values of T-1 of order 45 hours were recorded at room temperature, resulting from collisions of the atoms with the cell wall. The possibility of keeping nuclear polarization for several days opens up new possibilities in NMR He-3 magnetometry. Empirical means for characterizing the cesium coatings are proposed.
