Fission lithium
WebNatural lithium contains about 7.5 percent lithium-6. Both natural isotopes have anomalously low nuclear binding energy per nucleon (compared to the neighboring elements on the periodic table, helium and beryllium); lithium is the only low numbered element that can produce net energy through nuclear fission. WebThe most promising source of tritium seems to be the breeding of tritium from lithium-6 by neutron bombardment with the reaction. which can be achieved by slow neutrons. This would occur if lithium were used as the coolant and heat transfer medium around the reaction chamber of a fusion reactor. Lithium-6 makes up 7.4% of natural lithium.

WebOne lithium fission cycles turns two lithium-6 nuclei into three helium-4 nuclei, as two successive fissions involving protons as catalysts. This is very nice on paper because it involves only relatively common elements, seems amenable to a "chain reaction" (since you get back the catalyst protons, with extra energy), and is aneutronic, hence ... WebApr 23, 2024 · This sequence is often classed as a fusion reaction, although the last step does involve fission. Many writers prefer to just call it lithium burning. p + 3 6 L i 4 7 B e …
The discovery of nuclear fission occurred in 1938 in the buildings of the Kaiser Wilhelm Society for Chemistry, today part of the Free University of Berlin, following over four decades of work on the science of radioactivity and the elaboration of new nuclear physics that described the components of atoms. In 1911, Ernest Rutherford proposed a model of the atom in which a very small, d…
