| Abstract: | The multiparticle correlations of pious eastted from sources with different degreesof coherence are simulated by Monte Carlo method. The sensitivity of the dependenceof the multipion correlations in subevents with different multiplicities on the degreeof coherence of the pion-emitting source is investigated. The degrees of coherence ofthe sources for central collisions of 2.1A GeV Ne+Pb and 1.2A GeV Ar+KCl at theBevalac streamer chamber are analyzed. The results are compared with previous twopion interferometry results. |

| Keywords: | multipion correlations pion-emitting source degree of coherence. |
