Both isotopes of Copper, Cu-63 and Cu-65, are used to study copper metabolism and gastrointestinal diseases. Cu-63 is used for production of medical radioisotope Zn-62 and can also be used for the production of Cu-64 which is used in cancer diagnosis and treatment. Cu-65 has also been proposed as a precursor for the (cyclotron) production of Cu-64.

Naturally occurring isotopes

This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of copper are listed (including any which occur naturally) below.
Isotope Mass / Da Natural abundance (atom %) Nuclear spin (I) Magnetic moment (μ/μN)
63Cu 62.9295989 (17) 69.17 (3) 3/2 2.2233
65Cu 64.9277929 (20) 30.83 (3) 3/2 2.3817
Isotope abundances of copper
Isotope abundances of copper. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes.

Radiosotope data

Further data for naturally occuring isotopes of copper are listed above. This table gives information about some radiosotopes of copper, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.
