Abstract (data abstract)
FNAL-E272. PWA OF THREE-PION SYSTEMS PRODUCED IN THE COHERENT DISSOCIATION OF PI+ MESONS ON NUCLEAR TARGETS(CU AND PB) AT AN INCIDENT PI+ ENERGY OF 202.5 GEV. THIS GIVES FURTHER EVIDENCE FOR RESONANT CONTRIBUTIONS TO JP=1+ AND 0- WAVES AT 3PI MASSES BELOW 1.5 GEV. CR.= THIS CAN BE PLAUSIBLY IDENTIFIED WITH THE A1 AND RADIAL EXCITATION OF THE PION.
