TL;DR: In this article, the authors measured the reaction p d → 3 He η at a proton beam energy of 980 MeV, which is 88.5 MeV above threshold using the new ''germanium wall'' detector system.

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.

Absorption cross sections and efficiency of solid state detectors for light ions
Hartmut Machner,B. Razen +1 more
TL;DR: In this article, the absorption cross section for light ions at hundreds of MeV energy was studied and the results for the detection efficiency were condensed to simple formulae with only one parameter.
