The authors carried out a partial-wave analysis (PWA) of three-pion systems produced in the coherent dissociation of ..pi../sup +/ mesons on nuclear targets. The data have been analyzed for copper and lead targets at an incident ..pi../sup +/ energy of 202.5 GeV. This PWA provides further evidence for resonant contributions of J/sup p/ = 1/sup +/ and 0/sup -/ waves at 3..pi.. prime masses below 1.5 GeV, which can be plausibly identified with A/sub 1/ and ..pi.. mesons. The contribution from electromagnetic production of the A/sub 2/ has also been extracted, and an estimate for Coulomb production and radiative width of the A/sup 1/ has been obtained.
