By the method of stationary thermal flow, the measurements of effective thermal conductivity in the superfluid solution 3 He-4 He with initial molar concentration 9.8% 3 He in the temperature range 0.1-0.5 K have been carried out. At temperatures below 0.23 K, where the phase separation of the mixtu
Bound states and scattering resonances for a 3He-vacancy system in crystalline 4He are shown to exist. For realistic physical parameters the theory yields binding energies of ~ O. 1 K. It is found that the bound states and scattering resonances tend to enhance the diffusion coefficient of 3He. The e
Using a capacitive pressure gauge, the pressure of a constant-volume 4Hesample was measured in the temperature range 1.5-120 mK, at pressures of 25.3 bar (on the melting curve) and26.0 bar. A gradual pressure change occurring as a consequence of the ideal gas behavior of vacancies, or a pressure ano
