Abstract

Elements with even atomic number (Z) in the interval 50 ≤ Z ≤ 58 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 that _(52)Te and _(54)Xe indicates a substantial s-process contribution to the cosmic ray source. A significant abundance of _(58)Ce provides further support for this finding.
