Concentration dependence ofD, T 1, andT 2 for dilute solutions of3He in solid4He

Concentration dependence ofD, T 1, andT 2 for dilute solutions of3He in solid4He Measurements of the spin diffusion coefficientD and NMR relaxation timesT 1 andT 2 are reported for dilute solutions of3He in solid4He at two molar volumes, 20.95 and 20.7 cm3. The weakly interacting impuriton model, for whichD −1 is proportional to impurity concentration, is observed only at fractional impurity concentrationx 3 below 3 × 10−4. Forx 3 around 10−3,T 1 andT 2 are controlled by the formation and breakup of3He2 molecules. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

Measurements of the spin diffusion coefficientD and NMR relaxation timesT 1 andT 2 are reported for dilute solutions of3He in solid4He at two molar volumes, 20.95 and 20.7 cm3. The weakly interacting impuriton model, for whichD −1 is proportional to impurity concentration, is observed only at fractional impurity concentrationx 3 below 3 × 10−4. Forx 3 around 10−3,T 1 andT 2 are controlled by the formation and breakup of3He2 molecules.
