Abstract
Fifth order differential cross sections have been measured for the reaction during two experiments using the 8 MeV External Proton Beam at the Los Alamos Meson Physics Facility (LAMPF). The kinematically complete data were obtained at seven angular settings covering a range of four-momentum transfers. The protons were detected by MWPC counters on two arms which measured the reaction angles for both charged particles. A magnetic spectrometer measured the momentum of one of the protons. The measured cross sections were compared to calculations using a peripheral model of pion production. Results indicate that the data can be fit with a single value of the pion form factor parameter whose value is much larger than that predicted using optical model calculations.
