Abstract
An analysis of new data for the reaction [Formula Presented] at incident energies between 223 and 284 MeV is presented. [Formula Presented] cross sections are obtained via Goebel-Chew-Low techniques by extrapolation to the pion pole using the pseudoperipheral approximation. A consistency check between the present experimental results and previous experiments at higher energies is made using Roy equations. The isospin 0, S-wave [Formula Presented] scattering length was obtained using a variety of methods. The result obtained from a threshold expansion is [Formula Presented] (statistical) [Formula Presented] (systematic) in inverse pion mass units. It is shown that there are significant differ..
