Dear G4-s! I have a confusing situation with pions losing energy in so-called plastic (C8H8, density = 1.04 g/cm3, 440 mm thick). Predictet losses of pions in range of kinetic energy from 160 upto 300 MeV is about 100 MeV. But having geometry 4 "plates" 110 mm thikness each i see that pions lose more than predicted 20-25 MeV per plate. Some times the value is more than 100 MeV in each plate. Situation for protons is ideal. I'm using standart "General", "EM" phys. lists. Also there is an "Optical" physics list to simulate Cherenkov effect. Please give me you comments, Peter.
