Californium a nuclear explosion. Californium is not a major radionuclide at United States Department of Energy legacy sites since it was not produced in large quantities. Californium was once believed to be produced in supernovas, as their decay matches the 60-day half-life of Cf. However, subsequent studies failed to demonstrate any californium spectra, and supernova light curves are now thought to follow the decay of nickel-56. The transuranic elements from americium to fermium, including californium, occurred naturally in the natural nuclear fission reactor at Oklo, but no longer do so. Californium is produced in nuclear reactors and particle accelerators. Californium-250 is
Chemical equation a 2 before O, giving the balanced equation: This equation does not have any coefficients in front of CH and CO, since a coefficient of 1 is dropped. Generally, any chemical equation involving "J" different molecules can be written as: where "R" is the symbol for the "j-th" molecule, and ν is the stoichiometric coefficient for the "j-th" molecule, positive for products, negative for reactants (or vice versa). A properly balanced chemical equation will then obey: where the composition matrix "a" is the number of atoms of element "i" in molecule "j". Any vector which, when operated upon by the
