Beschreibungen/Notizen

• Pulsed NMR method is used to study phase separation kinetics in solid solution of He isotopes with 0.54 % 3 He at 100 mK and 20.55 cm 3 /mole. The growth of 3 He-enriched phase continued more than 30 hr with rate and separation temperature depending on sample history. 3 He diffusion in concentrated phase is quasi-one-dimensional with unusually large diffusion coefficient 10 -5 cm 2 /s, whereas magnetization changes and spin-lattice relaxation time coincide with those for bulk solid 3 He.
