An optical spark chamber and neutron time-of-flight spectrometer experiment studied the reaction π−p→π+π−n at incident pion momentum of 4.5 GeVc in the mass region of the f0 meson. Analysis of the data shows no evidence for anomalous structure in the f0 mass spectrum. The two-pion differential cross section in the f0 region is consistent with Wolf's one-pion-exchange model for momentum transfers (squared) −t≲0.7 (GeVc))2. The differential cross section is larger than that predicted at high momentum transfer, and may be attributed to natural-parity-exchange contributions as evidenced in the f0 decay distribution.
