I recently tried measuring the efficiency of a germanium array using GEANT4. The simulated results using G4GeneralParticleSource agreed well with the measured results; however, when substituting in G4ParticleGun and running, what I believe, is the exact same simulation, the efficiency estimates using GEANT4 are much lower. I've attached a zip drive containing my project. It should be relatively straight forward what needs to be uncommented or commented to switch between the two in B1PrimaryGenerator.cc/hh.
I tried posting a zip drive with the contained project with no luck. Attached are the PrimaryGenerator, Run, and RunAction classes from the project.
