|
| 46. | In 1961, Berkeley scientists claimed the discovery of element 103 in the reaction of californium with boron and carbon ions.
|
| 47. | Californium is not a major radionuclide at United States Department of Energy legacy sites since it was not produced in large quantities.
|
| 48. | In 1967, experiments were conducted to compare nobelium's chemical behavior to that of terbium, californium, and fermium.
