Abstract It is now well-known that the relative abundance of secondary cosmic ray nuclei which are produced by spallation in interstellar space depends on energies. The mechanism responsible for this energy dependence are not well understood because of the scarcity of data on the cosmic ray composition at energy above 50 GeV/amu. The University of Chicago experiment on the Spacelab-2 flown by the Space Shuttle in 1985 is aimed at the measurement of the elemental composition in this unexplored energy regime. Our latest results on the energy dependence of the secondary to primary abundance ratio using the pairs of elements B,C and N,O, are discussed.
