Abstract

Differential cross sections for charge exchange πp → π0n have been measured for momenta up to 50 GeV/c. The cross section falls as a power of energy. The forward scattering cone shrinks with increasing energy. The cross section for charge exchange at zero angle drops with momentum as P−0.81±0.05. The charge exchange cross section in the region of the second maximum decrease as P−2.8±0.1. The ϱ trajectory is described by a linear function α(t) = 0.56 + 0.97t in the interval 0 < −t-<1.5 (GeV/c)2.
