Cobalt-60 (60Co) is an unstable isotope of cobalt that decays by beta decay to the stable isotope nickel-60 (60Ni). 钴-60是一种不稳定的钴同位素,其会发生β衰变转变为稳定的镍-60。 WikiMatrix Cobalt 60 (Co 60) is a synthetic radioactive isotope of cobalt with a half-life of 5.27...
In 1938, John Livingood and Glenn T. Seaborg discovered cobalt-60. This isotope was famously used at Columbia University in the 1950s to establish parity violation in beta decay. Occurrence Cobalt occurs in copper and nickel minerals and in combination with sulfur and arsenic in the sulfidic co...
beta decayhalf-lifedatareduced transition probabilityThe photonuclear reaction 2D(γ,n) was utilized to measure the intensity of the weak 2,505 keV γ-ray in the decay of 60Co. A point-like source was used to cause the reaction in heavy water, and the neutrons generated were detected with...
Work by Verser on the angular correlation of gamma rays from Co/sup 60/ decay gave a correlation curve in disagreement with the theoreticai curve. A rerun of the cobalt-60 experiment was made to confirm the results obtained in the previous work. A comparison of the previous work confirms ...

In 1938, John Livingood and Glenn T. Seaborg discovered the radioisotope cobalt-60.[45] This isotope was famously used at Columbia University in the 1950s to establish parity violation in radioactive beta decay.[46][47] After World War II, the US wanted to guarantee the supply of cobalt ...
The main radioactive isotopes 57Co, 58Co, and 60Co decay with respective half-lives of 272 days, 71 days and 5.271 years, and emit γ rays. This document only deals with the stable isotope. Pure cobalt metal is steel-gray, shiny, hard, ductile, and brittle, and has magnetic properties...
