This paper describes the results of an experiment studying the reaction π+p → Δ++π0π0 using the Argonne National Laboratory 1.5 m streamer chamber combined with a lead glass hodoscope. The results of an energy‐independent amplitude analysis from threshold to 2.3 GeV are presented. In this analysis the f0(1270), the h0(2040), and a JP=2+ state at 1.8 GeV with a width of 0.280 GeV are observed. The amplitude ambiguity arising from analyses of π+π− → π+π− data in the 1.6 GeV region is resolved in favor of the β‐type solution. An energy‐dependent S‐wave phase shift analysis from 1.0 to 1.5 GeV is presented. |
