We have studied the viscosity of 3 He in the Al phase at various pressures with a vibrating wire viscometer in a magnetic field of 9.3 T. The data could be fitted surprisingly well using a simple model. The value of the minimum of the reduced viscosity is independent of pressure.
For the ftrst time 'He gas dissolved in solids (pyrex and suprasil glasses) has been studied by NMR. The chemical shifts are mainly determined by interaction with diamagnetic atoms of the glass structure and not by magnetic interaction with Fe'+ ions. In pyrex the relaxation times at 25Β°C are: T, ('
