Abstract
We present the results of phase separation under pressure in some dilute4He mixtures. The effect of pressure is to reduce the phase separation temperature for a given concentration. However, the general shape of all phase-separation curves seem to show that atT=0 K, no dilute4He solutions will exist. The analysis of our results using the isotopic impurity model shows also that4He-4He quasiparticle interaction is not detectable and so is certainly very small. The difference of behavior between dilute4He and dilute3He solutions has a statistical origin.
