Charge-Symmetry Test in the Reactionnpdπ0

Abstract
A sensitive test of the charge symmetry of nuclear forces is the angular symmetry about 90° of deuterons produced in the npdπ0 reaction. We predict a front-to-back asymmetry of about 0.8% in the Δ(3,3) resonances region. The asymmetry arises primarily from η0η mixing.
