The prompt gamma-ray spectrum of fission fragments (in the following PFGS) is important role for the dynamics of the fission process, as well as for nuclear engineering through gamma-ray heating in nuclear reactors. In this thesis the prompt gamma-ray spectrum from the spontaneous fission of ²⁴²Pu was measured. The gamma-quanta were detected with high time- and energy-resolution using LaBr₃ scintillators and High Purity Germanuim detectors in coincidence with spontaneous fission events of ²⁴²Pu fission chamber. This chamber was recently developed at the Helmholtz-Zentrum Dresden - Rossendorf. The aquired results show a much reduced statistical uncertainty in comparison with previous measurements. The PFGS measured with the HPGe detectors shows structures that allow conclusions about the nature of the gamma-ray transitions in the fission fragments.
The measured data can be used to test and improve statistical model calculations of the PFGS, e.g in the GEF-model.
