WebFissile Vs Fissionable. According to the fissile rule, heavy isotopes with 90 ≤ Z ≤ 100 and 2 × Z – N = 43 ± 2, with few exceptions, are fissile (where N = number of neutrons and Z = number of protons). "Fissile" is distinct from "fissionable." A nuclide capable of undergoing fission after capturing a neutron is referred to as ... Webfissions in any fissile materials. Whereas the method above measures the fissile object at a single position, tomography images the interior of an item by making transmission measurements from all angles around the object.
