Abstract

The new data on the elastic pp and single pion production reaction taken at the incident proton momentum of 1683MeV/c are presented. The data on the reaction are compared with predictions from the OPE model. To extract the contributions of the leading partial waves, the single-pion production data are analyzed in the framework of the event-by-event maximum-likelihood method together with the data measured earlier.
