    The decay scheme of 60 Co and 60m Co.. The diagram shows a simplified decay scheme of 60 Co and 60m Co. The main β-decay transitions are shown. The probability for population of the middle energy level of 2.1 MeV by β-decay is 0.0022%, with a maximum energy of 665.26 keV.

  4. Table of nuclides - Wikipedia

    en.wikipedia.org/wiki/Table_of_nuclides

    A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.

    The Alchymist, in Search of the Philosopher's Stone by Joseph Wright of Derby, 1771. The philosopher's stone [a] is a mythic alchemical substance capable of turning base metals such as mercury into gold or silver; [b] it was also known as "the tincture" and "the powder".

    en.wikipedia.org/wiki/Nuclear_transmutation

    The term transmutation dates back to alchemy.Alchemists pursued the philosopher's stone, capable of chrysopoeia – the transformation of base metals into gold. [3] While alchemists often understood chrysopoeia as a metaphor for a mystical or religious process, some practitioners adopted a literal interpretation and tried to make gold through physical experimentation.

  9. Breeder reactor - Wikipedia

    en.wikipedia.org/wiki/Breeder_reactor

    The second main component of spent fuel is transuranics (atoms heavier than uranium), which are generated from uranium or heavier atoms in the fuel when they absorb neutrons but do not undergo fission. All transuranic isotopes fall within the actinide series on the periodic table, and so they are frequently referred to as the actinides. The ...
