I am modeling experiment with easy NaI detector and point source of cesium.
Crystall of NaI have cylinder form and it is sensitive volume.
Physics list have description of next particles: gamma (Rayleigh Scattering, PhotoElectric Effect in Livermore model,Compton Scattering in Livermore model, Gamma Conversion in Livermore model),e+ (Ionisation in Livermore model, Bremsstrahlung in Livermore model),e- (Multiple Scattering, Pair Production, Ionisation, Bremsstrahlung).
I can get familiar to experimental spectrum of cesium with this settings, but it have narrow peak(idealized case). But i want measure energy resolution of detector, so i need wide peak.
How can i get blurring of peak? Maybe i don't consider another physics processes?
Thanks for help.
