Hi everyone, I'm an engineer and not a physicist, so forgive me if something sounds stupid. Question: Is it possible to know, which way products of nuclear fission (u-235) will go? Imagine a sheet of single (or few) atom layer crystal of U-235, that is irradiated by neutron source from the edge. Is it possible to predict where fission products will go? Is it better done experimentally or can be done theoretically or through simulation?
