Abstract

The isospin-forbidden reaction d+d→ $π^{0}$ $+^{4}$ He provides a very good test of the validity of charge symmetry. The forward differential cross section dσ/dΩ is estimated to be ≊0.12 pb/sr at a deuteron laboratory energy of 1.95 GeV. The assumed reaction mechanism is virtual η and η’ production and $π^{0}$ η and $π^{0}$ η’ mixing.
