A. ; Spalding, J. D. ; Stone, E. C. ; Vogt, R. E. Abstract High resolution measurements are presented for the elemental and isotopic composition of galactic cosmic ray B, C, N, and O nuclei with about 30-130 MeV/nucleon. The isotopes are separately resolved, and the resulting abundances are limited by statistical rather than systematic uncertainties. N is found to be significantly depleted in the cosmic ray source with respect to the solar system and local interstellar medium, and it is concluded that the N-14/O-16 limit is inconsistent with models in which a majority of cosmic rays are accelerated interstellar material.
