• Oliphant used electromagnetic separation to separate the isotopes of lithium.
• :It's worth mentioning what an underlying problem is : there are " no " radioactive isotopes of lithium with a usable half-life.
• An example of this kind of fission in a light element can occur when the stable isotope of lithium, lithium-7, is bombarded with fast neutrons and undergoes the following nuclear reaction:
• On March 1, 1954, the U . S . detonated its first practical thermonuclear weapon ( which used isotopes of lithium as its fusion fuel ), known as the " Shrimp " device of the Castle Bravo test, at Bikini Atoll, Marshall Islands.

Technicians loaded metal rods into the reactor containing an isotope of lithium metal; when these are struck by the neutrons that sustain the chain reaction, the lithium breaks up into tritium and helium.
• Certain light ( low atomic number ) primordial nuclides ( some isotopes of lithium, beryllium and boron ) are thought to have arisen not only during the Big Bang, and also ( and perhaps primarily ) to have been made after the Big Bang, but before the condensation of the Solar System, by the process of cosmic ray spallation on interstellar gas and dust.
