CaliforniumCalifornium, a trans-uranic element, was first discovered by Glenn Seaborg and collaborators at the University of California, Berkeley. Cf- 245 was first produced in 1950 by bombarding curium-242 with alpha particles (helium nuclei) accelerated in a cyclotron. Californium-245 is an alpha emitter with half-life 44 minutes. Californium-249 is produced by beta decay of berkelium-249. The heavier californium isotopes are produced by neutron bombardment of berkelium-249. Californium-252, with a half-life of 2.6 years, has an unusually high rate of spontaneous fission, with an abundant emission of neutrons. It has been used as a high-intensity neutron source for medical research.
