The archive with model

I model the response of a HPGe-detector to radionuclide radiation. I have modified extended example Geant4 rdecay02 in part of geometry and turn on CorrelatedGamma in BiasedRDPhisics: “G4DeexPrecoParameters deex = G4NuclearLevelData::GetInstance()->GetParameters();
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 Eu-152 the result is bad. For some reason there is a lot contribution of 688 keV - line in the modeled spectrum.

Hello Artur,

I have change the title to be more precise. 

The fix was introduced in Geant4 10.7patch03 and in the new 11.0 version, however, due to manpower limitation we have no chance to test Eu-152. If you can try these versions, please, report.
