Abstract
We report the results of measurements of longitudinal and transverse nuclear relaxation timesT 1 andT 2 in bcc3He at 300 mK and at a Larmor frequency of 3 MHz for molar volumes 22.6≤V≤24.9 cm3. It is found, even in this extended range of molar volumes, that the relaxation times increase withV as\({\text{T}}_{1,2} \propto {\text{V}}^{\gamma _{1,2} } \), with γ1=19±1 and γ2=18±1.5. This molar volume dependence has also been found in various thermodynamic data, including recent results of pressure measurements through the nuclear ordering temperature. This “universality” in molar volume dependence remains unexplained within the context of the present models of multiple exchange.
