ABSTRACT
We have performed measurements of the temperature dependence of the nuclear spin-lattice relaxation times ( T) for a wide range of He concentrations for dilute mixtures of He in solid He. The temperatures for phase separation are determined for He concentrations 500< x<2000 ppm for a molar volume V=20.7 cm. We report the temperature dependence of the nuclear spin-lattice relaxation times for He in the droplets formed after phase separation at low temperatures. The temperature dependence suggests that the interface He atoms responsible for the relaxation are degenerate, not solid-like.

    We have performed the simultaneous measurement of torsional oscillator and NMR in solid He with 10 ppm of He at 3.6 MPa. In this solid, NCRI response appears below about 400 mK. NMR measurement shows that there is the same kind of phase-separated He cluster which is found in our previous...

    Processes of spin-lattice relaxation in superfluid inclusions, formed during growth and rapid cooling of helium crystals, are studied by the pulse nuclear magnetic resonance method. Measurements of spin-lattice relaxation times were carried out using the two spin-echoes method. This allows to...
