Abundances relative to carbon of the elements silicon to nickel in the galactic cosmic radiationDiscussion of the abundances relative to carbon of the elements from silicon to nickel in the galactic cosmic radiation as measured by cosmic ray telescopes on the IMP-5 and IMP-7 satellites, in energy ranges between 40 and 450 MeV/nucleon depending on the species. The IMP-7 measurements are still to be considered only preliminary and do not yet fully exploit the resolution capabilities of that instrument. Calculations of the abundances to be expected in this charge range if the cosmic radiation traverses 6 g/sq cm of material after acceleration are presented, and the consequences which follow both for propagation models and for the chemical composition of the sources of the cosmic radiation are discussed.
