When a large nucleus absorbs a neutron, why does it undergo fission and not just emit the neutron?
For example: U-235 + neutron → U-236 → Ba-141 + Kr-92 + 3 neutrons + energy Why not just emit the neutron and return to the original nucleus: U-235 + neutron → U-236 → U-235 + neutron Sorry if the original question is badly worded, hopefully this makes more sense.
