Abstract

Elements with even atomic number (Z) in the interval 50 ≤ Z ≤ 56 have been resolved in the cosmic radiation using the Heavy Nuclei Experiment on the HEAO 3 satellite. The observation that _(50)Sn and _(56)Ba are more abundant than _(52)Te and _(54)Xe is inconsistent with a pure r-process cosmic-ray source. Adjustment of source abundances for an enhancement of those elements with a low first ionization potential does not change this conclusion.
