Differential Cross Sections Measurement for the $pp\to dπ^+$ Reaction at 850 MeV/c
The present data support a large anisotropy in accordance with phase shift predictions and in contrast to another recent experiment.

Simultaneous Measurements of the $p+d\to (A=3) +π$ Reactions
A stack of annular detectors made of high purity germanium was used to measure simultaneously $pd\to {^3H} π^+$ and $pd\to {^3He} π^0$ 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 $pd\to {^3He} π^0$ 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.

Meson Production in p+d Reactions
The production of neutral and charged pions as well as eta mesons is studied in the Delta and N* resonance region, respectively. Heavy A=3 recoils were measured with the GEM detector. The differential cross sections covering the full angular range are compared with model calculations.
