lithium-7 (uncountable)
(physics) A stable isotope, 3Li, having three protons and four neutrons, that makes up about 93% of natural lithium.
Examples
Reactors that use lithium-7 heat water under high pressure and transfer heat through heat exchangers that are prone to corrosion.
Fusion of lithium-7 and a proton occurs producing two helium-4 nuclei.
The difference is whether the lithium-7 produced is in the ground state or an excited state, respectively.
The neutrons released from the fission of the sparkplug split lithium-6 into tritium plus helium-4 and lithium-7 into helium-4 plus tritium plus one neutron.
This deficit of larger atoms also limited the amounts of lithium-7 produced during BBN.
