However, when one wants to calculate the detection efficiency for various energies considering radioactive isotopes, the coincidence effects become important. Can this effect be taken into account with other scorings (e.g. EVENTBIN or mgdraw)?
While I’m not an expert on HPGe detectors, if I understood correctly these correction factors can be calculated with Monte Carlo simulation, simulating the individual lines separately and then comparing it to the results obtained with the radionuclide. Then you can apply them during the analysis of the real data.
I don’t think it is possible to apply the correction factors during the FLUKA run, because they have to be applied only for the peaks, but not for the background contribution coming from higher energy lines.
