Fabrocini, A.Polls Martí, Artur2009-10-202009-10-2019820163-1829https://hdl.handle.net/2445/9737The ground-state properties of the 3He-4He mixture are investigated by assuming the wave function to be a product of pair correlations. The antisymmetry of the 3He component is taken into account by Fermi-hypernetted-chain techniques and the results are compared with those obtained from the lowest-order Wu-Feenberg expansion and the boson-boson approximation. A little improvement is found in the 3He maximum solubility. A microscopic theory to calculate 3He static properties such as zero-concentration chemical potential and excess-volume parameter is derived and the results are compared with the experiments.8 p.application/pdfeng(c) The American Physical Society, 1982SuperfluïdesaHeli líquidSuperfluidityLiquid heliuminfo:eu-repo/semantics/article12509info:eu-repo/semantics/openAccess
