None production of GenericIon 

Forum: Particles

From: Sara Vecchio <sara.vecchio@pi.infn.it>

By shooting protons on PMMA through a very complicated beam line (made of different materials), when I look the tracking verbosity I see a large variety of ions: C12, C13, O16, N15, O17, Be8, B11, Al27.. No C11, O15, C10 appear but this may be due by a wrong physics list, since I've seen them in previous simulations.

But I also see, quite often, the tracking of a "Generic Ion" (I've not yet checked whether they can also decay). If all the isotopes are identified by theirname and mass number.. what does the GenericIon stand for? Can this behaviour due to the physics list, too?
