Examples

  • An atom of lithium-7 plus an atom of hydrogen-1 yields two atoms of helium-4 and plenty of energy.

    Unwise Child Randall Garrett 1957

  • This resultant extra fuel (both lithium-6 and lithium-7) contributed greatly to the fusion reactions and neutron production and in this manner greatly increased the device's explosive output.

  • Contrary to expectations, when the lithium-7 isotope is bombarded with high-energy neutrons, it absorbs a neutron then decomposes to form an alpha particle, another neutron, and a tritium nucleus.

    Booman Tribune 2010

  • They considered only the lithium-6 isotope in the lithium deuteride secondary to be fissionable; the lithium-7 isotope, accounting for 60% of the lithium content, was assumed to be inert.
