Coherent π[sup 0]-photoproduction on the deuteron including polarization observables

Abstract

Coherent π0‐photoproduction on the deuteron including polarization effects in the energy region from π‐threshold up to 1 GeV is studied using an enhanced elementary pion photo‐production operator on the free nucleon and a realistic NN potential model for the deuteron wave function. Results for double polarization observables are predicted for which the sensitivity to various models for the elementary pion photoproduction amplitude is investigated. We find considerable dependence of the results on the elementary amplitude. In addition, results for differential cross section are predicted and compared with the experimental data from TAPS and a satisfactory agreement was found.
