Lithium Isotope

Lithium has two stable isotopes, 6 Li and 7 Li, which have abundances of 7.5% and 92.5%, respectively. Lithium is a soluble alkali element. Because its ionic radius is small (0.78 Å), it behaves more like magnesium (0.72 Å than the alkalis). Li + tends to substitute for Al 3+, Fe 2+, and especially for Mg 2+.

Isotopes of lithium

OverviewDecay chainsList of isotopesIsotope separationLithium-3Lithium-4Lithium-6Lithium-7

While β decay into isotopes of beryllium (often combined with single- or multiple-neutron emission) is predominant in heavier isotopes of lithium, Li and Li decay via neutron emission into Li and Li respectively due to their positions beyond the neutron drip line. Lithium-11 has also been observed to decay via multiple forms of fission. Isotopes lighter than Li decay exclusively by proton emission, as they are beyond the proton drip line. The decay modes of the two isomers of Li are …

Boosted fission weapon

This fission then releases energy and also neutrons, which then create more tritium from the remaining lithium-6, and so on, in a continuous cycle. Energy from fission of uranium-238 is useful in weapons: both because depleted uranium is much cheaper than highly enriched uranium and because it cannot go critical and is therefore less likely to be …

Does lithium-6 "decay" when hit by a neutron?

2. It is a prompt reaction, Li6 (n,T)He4 (and the major portion of the total neutron cross section). I''m not sure ''decay'' or ''neutron activation'' is entirely appropriate, since those indicate some uncertainty in exactly when it will occur. Here the neutron and the Li6 collide, and the T and He4 come out with no delay.

Nuclear fusion–fission hybrid

Fusion–fission designs essentially replace the lithium blanket of a typical fusion design with a blanket of fission fuel, either natural uranium ore or even nuclear waste. The fusion neutrons have more than enough energy to cause fission in the 238 U, as well as many of the other elements in the fuel, including some of the transuranic waste elements.

Out of curiosity, has anyone ever looked into a Li-6 fission …

I''m no engineer, but since fission is about 200 MeV per a reaction, it would stand to reason that you would need 40x the reactions in a traditional fission reactor to produce comparable power. Since a normal reactor is like 1.6E19 ish reactions per second for 500 mWth a Li6 fission reactor would be like 6.2E20 reactions per a second for 500 mWth.
