A fourfold segmented High Purity Germanium detector can be used as Compton-polarimeter [1] in order to derive parities from photon scattering experiments. In order to calibrate the analyzing power of the polarimeter, (p,pγ), (p,αγ), and (α,γ) reactions have been studied in detail.
We present a complete set of results up to a γ energy of 10 MeV.
