Bose Einstein correlations of neutral pion pairs at LEP
  With the OPAL detector at LEP we measured at energies around the Z0 peak the Bose-Einstein Correlations (BECs) of neutral pion pairs. We compare the results of this measurement with former results obtained at LEP for hadrons including those obtained from Fermi-Dirac Correlations (FDCs).
