Fabrocini, A.Polls Martí, Artur2009-10-202009-10-2019820163-1829https://hdl.handle.net/2445/9736We report variational calculations, in the hypernetted-chain (HNC)-Fermi-HNC scheme, of one-body density matrices and one-particle momentum distributions for 3He-4He mixtures described by a Jastrow correlated wave function. The 4He condensate fractions and the 3He strength poles are examined and compared with the Monte Carlo available results. The agreement has been found to be very satisfactory. Their density dependence is also studied.4 p.application/pdfeng(c) The American Physical Society, 1982Matèria condensadaHeliTeoria quànticaCondensed matterHeliumQuantum theoryinfo:eu-repo/semantics/article12507info:eu-repo/semantics/openAccess
