TL;DR: In this paper, a stack of annular detectors made of high-purity germanium was used to measure simultaneously pd → 3H π + and pd→ 3He π 0 differential cross sections at beam momenta of 750, 800, and 850 MeV/c over a large angular range.

TL;DR: In this article, the total and differential cross sections for the reactions p + d → 3He + m0 with m=π, η and p +d → 3H+π+ were measured with the GEM detector at COSY for beam momenta between threshold and the maximum of the corresponding baryon resonance.

TL;DR: A stack of annular detectors made of high-purity germanium was developed in this paper for meson production reactions close to threshold, and the detectors are position sensitive with radial structures, the first one (Quirl) is double-sided position sensitive defining 40 000 pixels, the following three (E1, E2 and E3) have 32 wedges each.
