Helium-3 nuclear spin relaxation times T1, T2, and Tip have been measured for 3He-4He solid mixtures at the exchange plateau region (~ O. 5 K). The 3He concentrations x3 of the samples were 7.2, 2.9, 1.8, 1.4, 0.67, 0.65, and 0.22 %, and their molar volumes varied between 19.9 and 20.9 cm3 /mole in
We report pulsed nmr experiments on a 2.6% 10 mK and 1 K. 3He-4He solution at 347 MHz and at temperatures between By analysing the phase of the spin echoes we have determined the spin rotation parameter. The decay of the transverse magnetisation is not consistent with the Leggett-Rice theory.
