I would like to read out which and how many unstable elements are created in a 3d volume. Is there an easy way of doing so? What I would like to have is some kind of phase space, but not recording the outgoing particles, instead recording the element distribution within a given phantom. Do you know if there is an easy way to do so? That is, without writing a new actor?
