Chemical composition of cosmic rays with Z greater than or equal to 30 and E greater than or equal to 325 MeV/NResults are presented on the chemical composition of VVH cosmic rays from a series of six high-altitude balloon flights of a large-area, high-resolution electronic detector. The charge composition in the 32 less than or equal to Z less than or equal to 45 interval is found to be inconsistent with S-process nucleosynthesis. The energy spectrum of particles with Z greater than or equal to 32 between 600 and 1500 MeV/N at the top of the atmosphere is measured and is found to be consistent with the 25 less than or equal to Z less than or equal to 27 group within experimental error.
