You don't need this if fast particles are the trigger. As I said previously, the natural branching will automatically lead to a cone shape, because more energy is released at the end than at the start (more reactions at the end), and it increases as it goes from start to end. The actual angle of the cone will depend on how many new events an originating event triggers on average. If the number is small, then you end up with a deep narrow cone. If large, then a wide shallow one. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
