| Abstract: | The results of a wire chamber spectrometer experiment studying 1 (890) production in the reaction K?p→ K?π+n at 13 GeV are presented. Strong forward structure is observed for |t|< m2π in the s-channel density matrix elements and differential cross section. These features are similar to those observed in π?p→?0n data and are characteristics of π exchange. In contrast in the intermediate, |t| ～ 0.2 GeV2, and large momentum transfer regions 1 (890) production is demonstrated by the natural parity ??A2 exchange contribution. |
