Good day all! I model the response of a HPGe-detector to radionuclide radiation. I have modified example rdecay02 in part of geometry and turn on CorrelatedGamma in BiasedRDPhisics: “deex->SetCorrelatedGamma(true);”, file PhisicsList stay unmodified. I have got a good match with the experimental data for Co-60 and Ba-133. But for the Bi-207 the result is bad. For some reason there is no contribution of 1063 keV - line in the modeled spectrum. There is no full absorption peak, Compton scattering, peaks of single and double escape, peak for 1063 keV + 569 keV = 1633 keV (the most strong and intensive cascade) and etc. Is there some error in modeling from my side or from Geant4 side either? Counting on your help.
