Abstrakt: The Bose-Einstein interference effect is studied using 7333 events of ¯pp-interactions withnch?6 at 22·4 GeV/c. An essential dependence of the strength of this effect on the pion pair velocity is observed. An indication is obtained that processes with essentially different time characteristics (t<1 fm and t>2 fm) contribute to ¯pp-interactions at 22·4 GeV/c. The interpretation based on abundant resonance production in high energy collisions is discussed.
