Hi Andreas, The message from G4NuclearLevelManager does not indicate a problem; rather it informs you that data from certain nuclear fragments do not exist. This is most often the case for nuclei far from stability which have never been measured. In this case, Geant4 will still generate gammas, but not with discrete energies. The message from G4Fragment is a warning which indicates that there is some energy non-conservation going on. This is a relatively rare shortcoming of the model involved, and not of the physics list you have used, or your setup. As to the "unsupported particle" message: what particles does the MULASSIS layer instantiate? The cross section code being accessed only supports pi+, pi-, pi0, p, n, K+, K-, K0L, K0S, d, t, alpha, lambda, sigma+, sigma-, sigma0, xi0, xi-, omega- and the anti-nucleons and anti-hyperons. Perhaps MULASSIS is trying to get a cross section for some other ion like 3He or maybe an eta. Dennis
