Abstract

We present a partial-wave analysis of the polarization data for the reaction \stackrel\ensuremath→p\stackrel\ensuremath→p\ensuremath→pp\ensuremathπ⁰, based solely on the recent measurements at the Indiana University Cyclotron Facility for this channel. Methods for an improved analysis are discussed. We compare the extracted values to those from a meson exchange model. The fit leads to a \ensuremathχ² per degree of freedom of 1.7.
