Search for ΔI=2 Electromagnetic Currents in Pion Photoproduction
Abstract
Differential cross sections for the reactions γp-->π0p, π+n and γn-->π-p, π0n were measured in a single experiment using tagged photons in the energy region 240-450 MeV incident on 1H2 and 2H2 targets. Results of the measurements of the ratios π0nπ0p and π-pπ+n are presented. The ratio of isotensor to isovector amplitude is found to be 0.00+/-0.02.
