Plutonium 241. 241 Pu is a fissile isotope, which means 241 Pu is capable of undergoing fission reaction after absorbing thermal neutron. Moreover 241 Pu meets also alternative requirement that the amount of neutrons produced by fission of 241Pu ( ~2.94 per one fission by thermal neutron) is sufficient to sustain a nuclear fission chain reaction. Plutonium-241 (241 Pu or Pu-241) is an isotope of plutonium formed when plutonium-240 captures a neutron. Like some other plutonium isotopes (especially 239 Pu), 241 Pu is fissile, with a neutron absorption cross section about one-third greater than that of 239 Pu, and a similar probability of fissioning on neutron absorption, around 73%. Based on the results obtained in this laboratory and the values reported by other laboratories, a half-life value of 14.4±0.1 y is recommended. The paper reviews the past history, puts forth the present status, highlights the current trends for studying the effect of chemical composition of plutonium on the half-life of 241 Pu and presents the The plutonium isotopes listed below are "fissionable," which means that the nuclei can be split into two fragments, called fission products. In addition to being fissionable, plutonium-239 and plutonium-241 are "fissile" - that is, they can be split by neutrons of very low (ideally zero) energy. This means that they can be assembled into a […] Responsibility Edited by J.A. Prins. Imprint Amsterdam, North-Holland Pub. Co.; New York, Interscience Publishers, 1965.
