Abstract Observations of the isotopic composition of the elements carbon, nitrogen, oxygen, neon, magnesium, silicon, sulfur, calcium, iron and nickel are reviewed and “best” values of selected isotope ratios are derived from the collected data. A simple model of cosmic ray propagation is employed to deduce cosmic ray source abundance ratios both from these best values and from the observations made in a recent high resolution satellite experiment. General features of the cosmic ray source composition are discussed, with emphasis on the enhanced abundances of various neutron rich nuclides and on the distinctly non-solar character of the nitrogen isotopic abundances.
