The effective mass at equilibrium density, m; /m4 = 1.21, is in very good agreement with the recent experimental determination by Edwards et al. The three-particle correlations appear to give a small contribution to the effective mass and different approximations for the three-particle distribution function give almost identical results for m: /m4.4 p.application/pdfeng(c) The American Physical Society, 1994Estadística quànticaHeli líquidQuantum statisticsLiquid heliumEffective mass of one 4He in liquid 3 Heinfo:eu-repo/semantics/article94794info:eu-repo/semantics/openAccess
