Isotopes of californium Isotopes of californium Californium (Cf) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be synthesized was Cf in 1950. There are 20 known radioisotopes ranging from Cf to Cf and one nuclear isomer, Cf. The longest-lived isotope is Cf with a half-life of 900 years. Californium-252 (Cf-252) undergoes spontaneous fission and is used in small sized neutron sources. Fission neutrons have an energy range of 0 to 13 MeV with a mean value of 2.3 MeV and a most probable value of
Californium (video game) the approach of showing the bubbles of alternate realities was "extraordinary as a piece of level design", while some of the attempts at meta-fictional narration had been better accomplished in "The Stanley Parable". Californium (video game) Californium is an exploration game co-developed by Darjeeling and Nova Productions, and released in February 2016 for Microsoft Windows and OS X. "Californium" was developed as a tribute to science-fiction author Philip K. Dick on the 30th anniversary of his death. The player controls Elvin Green, a struggling writer dealing with family matters, as he discovers the means to manipulate reality, and explores several
