The nuclear spin thermal relaxation time, T/sub 1/, of He/sup 3/ nuclei was measured at 1.2 and 3.0 deg K in pure liquid He/sup 3/ under its saturated vapor pressure. The measured times are those characteristic of the bulk liquid. T/sub 1/ is 300 seconds at 1,2 deg and increases to 550 seconds at 3.0 deg K. These results are in fair agreement with the Bloembergen, Purcell, and Pound theory. For a 12% solution or He/sup 3/ in He/sup 4/ under its saturated vapor pressure, T/sub 1/ is about 2000 seconds and does not show any sharp change at the lambda point, In pure He/sup 3/ gas at 4.2 deg K and 1000 mm pressure, T/sub 1/ is at least 1000 seconds. In dilute solutions at 1.25-K, T/sub 1/ is at least 90 minutes for a 3.5% solution and at least 120 minutes for a 1.7% solution. (auth)
