摘要：

We have studied the reaction p+p-->p+p+pi-0 from 320 to 500 MeV by detecting the gamma rays from pi-0 decay in coincidence in two large NaI crystals. The obtained differential and total cross sections of the pions are in agreement with previous measurements but are of a higher precision. We have also measured the pion analyzing powers; the first measurement of this observable. Our results are compared with those for the reactions np-->NN-pi+/- with confusing conclusions concerning the contribution of sigma-01, the zero isospin pion production channel.
