Californium is a synthetic chemical element; it has symbol Cf and atomic number 98. It was first synthesized in 1950 at Lawrence Berkeley National Laboratory...

Californium (98Cf) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes...

berkelium-249 isotope emits low-energy electrons and thus is relatively safe to handle. It decays with a half-life of 330 days to californium-249, which...

its properties is difficult due to 253Es's decay to berkelium-249 and then californium-249 at a rate of about 3% per day. The longest-lived isotope of einsteinium...

2002 and two more in 2005) produced via collisions of californium-249 atoms and calcium-48 ions. 249 98Cf + 48 20Ca → 294 118Og + 3 n . In 2011, IUPAC evaluated...

halides, including californium(III) fluoride (CfF3), californium(III) chloride, and californium(III) iodide (CfI3), the californium atom has an oxidation...

bombarding curium-248 or californium-249 with carbon-12: the latter method is more common. Irradiating a 350 μg cm−2 target of californium-249 with three trillion...

for element 106 using oxygen-18 projectiles and the previously used californium-249 target was conducted. Several 9.1 MeV alpha decays were reported and...

California, in 1974. They created seaborgium by bombarding atoms of californium-249 with ions of oxygen-18 until seaborgium-263 was produced. During the...
