The extracted total cross sections for the $pd\to {^3He} π^0$ 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 $η={p^{cm}_π}/m_π$ yields $2.11\pm0.08$ indicating that a deviation from isospin symmetry is very small.23 pages, latex, 15 figuresNuclear Experimenttext
