Hi, I am using the G4GeneralParticleSource to generate my primary particles. What I want to simulate is the spectrum of a Co60 source and another one of a Eu152 source. So what I do in the macro file is: # for Co60 /gps/particle ion /gps/ion 27 60 0 0. /gps/ene/mono 0.025 eV # and for Eu152 /gps/particle ion /gps/ion 63 152 0 0. /gps/ene/mono 0.025 eV and I get good spectra. But now I wondered about the angular distribution of the emitted gammas. So here are my questions: First: Is the angular distribution implemented? (eg: will the two gammas from the Co60 ion-source be emitted corresponding to the proper angular distribution, or just isotropic?) Second: If they are emitted uncorrelated (isotropic), how can I implement such a angluar correlation using G4GeneralParticleSource (if it is possible at all...)? Thanks very much for your help, Chris
