The results are given of investigation of the two-particle correlations of ..pi../sup 0/ mesons emitted with close momenta in ..pi../sup -/Xe interactions at the incident-pion momentum 3.5 GeV/c. The interference correlations of ..pi../sup 0/ mesons are observed. The size of the region of emission of negative pions is determined and an estimate of the time of their generation is given: /sup 1//sup ///sup 2/ = 1.2 +- 0.3 fm, ctau = 0.8/sup +0.4//sub -0.3/ fm. These values are consistent with the results obtained in hadron-hadron interactions but are lower than the r and ctau values in nucleus-nucleus interactions at the same energies.
