Abstract: | The number density of dilute 3He-4He solutions under saturated vapor pressure is calculated within the framework of quantum hydrodynamics. For temperatures T small compared to the 3He Fermi temperature TF, results are given for 3He concentrations large enough to manifest 3He quasiparticle interactions. The nondegenerate regime (TTF) is also considered in the limit of small 3He concentration. Relevance to experimental determination of quasiparticle energies and interactions is emphasized.Supported by the National Science Foundation under Grant No. GP-40831. |
