Radioactive Isotopes of Cobalt

Physical Review, 1941
T HE recent mass spectrographic investigation of the cobalt isotopes by Mitchell, Brown, and Fowler,' showing that Co69 is the only stable isotope of cobalt, taken together with our recently acquired transmutation data, now makes it possible for us to make isotopic assignments for all the cobalt radioactivities with almost complete certainty. Tentative

Long-Lived Cobalt Isotopes Observed in Fallout

Science, 1958
Analyses of three samples of fall-out revealed the presence of the induced radioisotopes Co/sup 57/, Co/sup 58/, and Co/sup 60/. The amounts of these radioisotopes present in the samples would not constitute an internal hazard compared to the abounts of Sr/sup 90/ present in the samples.

New isotopes of cobalt; Activation cross-sections of nickel, cobalt, and zinc for 14.8 MeV neutrons

Nuclear Physics (journal), 1960
Absolute neutron activation cross-sections at 14.8 Mev were measured for the five stable nickel isotopes, for cobalt, and for zinc, based on comparison with the Cu/sup 63/(n,2n)Cu/sup 62/ reaction (556 mb), the Cu/sup 65/(n,2n)Cu/sup 64/ cross-section (1000 mb), and the Al/sup 27/(n, alpha )Na/sup 24/ reaction (115 mb).

56,57,60CoFe NMR/ON, hyperfine anomalies and γ-factors of cobalt isotopes

Hyperfine Interactions, 1987
The results of NMR/ON measurements on56'57'60Co isotopes in iron are presented. To avoid the uncertainties caused by local demagnetizing field inhomogenities the measurements on two cobalt isotopes in one sample have been carried out. The values of nuclearγ-factor ratiosγ57/γ60 = 1.805 (20),γ60/γ56 = 0.761 (20),γ56/γ57 = 0.726 (20) and hyperfine ...

Isotopic exchange in the cobaltous-cobaltic system in perchloric acid

Journal of Inorganic and Nuclear Chemistry, 1962
Systematic investigations are reported on the isotopic exchange in the cobaltous-cobaltic system using cobalt-60. Ammonia and ethylenediamine were found to be satisfactory quenchers of this fast exchange, even though some zero-time exchange was observed.
