The arriving abundances of a variety of cosmic-ray nuclides consist of comparable amounts of primary material produced by stellar nucleosynthesis and secondary matter resulting from fragmentation of heavier nuclei by collisions during interstellar propagation. We discuss a technique for extracting the primary and secondary contributions that takes advantage of energy spectra of individual nuclides available from the Advanced Composition Explorer mission, a data base of measured and calculated fragmentation cross sections, and the leaky box model of interstellar propagation.
