List of fissile isotopes

WebNuclei such as 235 U that lead to fission following the thermal neutron absorption are called fissile nuclei. For heavy nuclides with an atomic number of higher than 90, most fissile isotopes meet the fissile rule: Fissile isotopes have 2 x Z – N = 43 ± 2 (example for 235U: 2 x 92 – 143 = 41) WebA fissile isotope, such as uranium-235, is one that is sufficiently large and unstable to undergo such a chain reaction, as opposed to the more common and less unstable uranium-238. Ponytail fear that her raspberries have too many unstable isotopes so that her fields risk undergoing a similar fission-driven chain reaction.
