Newcomb, P. C.A.

A hydrogen bubble chamber was used to investigtae pi /sup +/-p interactions at 600 Mev. There were 1738 good events. of which 71.9 plus or minus 0.8% were elastic. Partial waves up to at least D/sub 3/2/ are required to fit the elastic angular distribution. The inelastic events were almost entirely single-pion production. The ratio (p + 0)/(n++) was found to be 5.5 plus or minus 0.8, which agrees well with 4.9 predicted by the (3/2, 3/2) pionnucleon isobar model of Olsson and Yodh. It is also consistent with 6.5 predicted by Sternheimer and Lindenbaum. The pion momentum spectra and the pi -- pi Q-value distributions also support the Olsson and Yodh model. Thus the mechanism for single-pion production at 600 Mev. Angular distributions for the single-pion-production data are presented. (auth)
