Isotopes of cobalt - Wikipedia
The isotopes of cobalt range in atomic weight from 50 Co to 78 Co. The main decay mode for isotopes with atomic mass less than that of the stable isotope, 59 Co, is electron capture and the main mode of decay for those of greater than 59 atomic mass units is beta decay .
Cobalt Isotopes - List and Properties - ChemLin
List, data and properties of all known isotopes of Cobalt. All atomic nuclei of the chemical element cobalt are summarized under cobalt isotopes; these all consist of an atomic nucleus with 27 protons and, in the uncharged state, 27 electrons. The difference between each cobalt isotope is based on the number of neutrons in the nucleus.

The isotopes of cobalt range in atomic weight from 50 u (50 Co) to 73 u (73 Co). The primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, 59 Co, is electron capture and the primary mode of decay for those of greater than 59 atomic mass units is beta decay .

The cobalt isotope is used to label cobalt in vitamin B12 to monitor how the body processes this essential vitamin [224]. 57 Co delivers the smallest radiation dose of all the cobalt isotopes. As a result, it has been used in the past for imaging and estimating organ size and location and in evaluating tumors of the head and neck [75], [99 ...
radioactive cobalt isotopes were produced using heavy-ion fusion evaporation (FE), light-particle reac-tions (LP), proton-capture reactions (PC), photo-nuclear reactions PN), deep-inelastic reactions (DI), and projectile fragmentation or fission (PF). The stable isotope was identified using mass spectroscopy (MS).
