text: The term 'fissionable' applies to isotopes that can be made to undergo fission.
text: In general, isotopes of odd mass numbers are more likely to absorb a neutron, and can undergo fission upon neutron absorption more easily than isotopes of even mass number.
text: An article explaining the discovery was prepared by the team and sent to the Physical Review to be published in March 1941, but the paper was withdrawn after the subsequent discovery that an isotope of the new element, plutonium-239, could undergo fission and be used as fuel for an atomic bomb.
text: In general, isotopes with an odd number of neutrons are both more likely to absorb a neutron, and more likely to undergo fission on neutron absorption, than isotopes with an even number of neutrons.
text: In general, isotopes of odd mass numbers are more likely to absorb a neutron, and can undergo fission upon neutron absorption more easily than isotopes of even mass number.
text: Many isotopes of uranium can undergo fission, but uranium-235, which is found naturally at a ratio of about one part per every 139 parts of the isotope uranium-238, undergoes fission more readily and emits more neutrons per fission than other such isotopes.
