Description
- Content Description: The results of an investigation of the isotopic composition of galactic cosmic ray carbon, nitrogen and oxygen (E approx. 80 to 230 MeV/amu) made using the U.C. Berkeley HKH instrument aboard the ISEE-3 spacecraft are reported. The combination of high mass resolution and a large statistical sample makes possible a precise determination of the relative isotopic abundances for these elements. In local interplanetary space we find: /sup 13/C/C = 0.067 +- 0.008, /sup 15/N/N = 0.54 +- 0.03, /sup 17/O/O < 0.027, and /sup 18/O/O = 0.019 +- 0.003.
