Cross sections and decay distribution moments are presented for the reaction p p → Δ ++ Δ ++ at 3.6 GeV/ c , and compared with previously published data at 9.1 and 12 GeV/ c . With the aid of the quark model, we have isolated the natural and unnatural parity exchange contributions and shown them to accord with expectations based on simple Regge-pole exchanges.
DOUBLE RESONANCE PRODUCTION IS 62 +- 2 PCT OF CHANNEL.
DIFFERENTIAL CROSS SECTION INTERCEPT AND SLOPE. EVENT SAMPLE DEFINED BY CUTS ON LONGITUDINAL PHASE SPACE PLOT.
