✦ Synopsis

A simple model of isospin and charge symmetry breaking due to external π 0 -η meson mixing is presented. It is based on amplitudes extracted from the available experimental data for pd → 3 He π 0 , pd → 3 He η and dd → 4 He η reactions. Predictions of the strength of isospin symmetry breaking in pd → 3 H π + / 3 He π 0 reactions are given. Within the same model, the cross section for the charge symmetry breaking dd → 4 He π 0 reaction is calculated.
