Two-particle correlations of /ΛΛ and /Λ ̄Λ ̄ pairs have been studied in multihadronic Z decays recorded with the ALEPH detector at LEP in the years from 1992 to 1995. The correlations were measured as a function of the four-momentum difference Q of the pair. A depletion of events is observed in the region /Q<2 GeV which could arise from the effects of Fermi-Dirac statistics. In addition the spin content of the /Λ pair system has been determined. For /2 GeV the fraction of pairs with spin one is consistent with the value of 0.75 expected for a statistical spin mixture, whilst for /Q<2 GeV this fraction is found to be lower. For /ΛΛ ̄ pairs, where no Fermi-Dirac correlations are expected, the spin one fraction is measured to be consistent with 0.75 over the entire analysed Q range.
