Abstract
A simple model of isospin and charge symmetry breaking due to external pi(0 )-eta meson mixing is presented. It is based on amplitudes extracted from t he available experimental data for pd --> He-3 pi(0), pd --> He-3 eta and d d --> He-4 eta reactions. Predictions of the strength of isospin symmetry b reaking in pd --> H-3 pi(+)/He-3 pi(0) reactions are given. Within the same model, the cross section for the charge symmetry breaking dd --> He-4 pi(0 ) reaction is calculated. (C) 2000 Elsevier Science B.V. All rights reserve d.
