Abstract:A stack of annular detectors made of high-purity germanium was used to measure simultaneously pd → 3H π+ and pd → 3He π0 differential cross sections at beam momenta of 750 MeV/c, 800 MeV/c, and 850 MeV/c over a large angular range. The extracted total cross sections for the pd → 3He π0 reactions bridge a gap between near threshold data and those in the resonance region. The ratio of the cross sections for the two reaction channels taken at the same η=pcmπ/mπ yields 2.11±0.08 indicating that a deviation from isospin symmetry is very small.
