Historical Information
Californium was discovered in 1950 at the University of Berkley in California. It was man-made by Thompson, Ghiorso, Seaborg, and Street by bombarding very small amounts of 242Cm with 35MeV helium ions in a 60-inch cyclotron.
This is pretty much all the information I have on how Californium was discovered, but if you want to know more about what has been done with Californium so far, you might want to go back to my main page and check some other links.
