Sumario:After summarizing the properties of the so-called Dalitz Array (DA), which is a genuine characteristic of a resonance. The authors determine those of the well known omega , phi and A/sub 2/ resonances produced in the K/sup -/p to pi /sup +/ pi /sup -/ Pi /sup 0/ Lambda final state at 4.2 GeV/c. A tentative measurement of the DA of the A /sub 1/ meson produced backwards in the reaction K/sup -/p to pi /sup +/ pi /sup +/ pi /sup -/ Sigma /sup -/ is also presented. The data for this analysis come from the high statistics (130 event/ mu b) experiment performed by the ACNO Collaboration. (10 refs).
