The Skylab ultraheavy cosmic ray experimentCosmic-ray nuclides of charge Z from 65 to 110 were detected with a Lexan sheet array mounted on the spacecraft. The charge distribution showed 83 nuclei of Z not less than 65, 6 nuclei of charge not less than 90, one with Z not less than 93, and no superheavy nuclei (Z not less than 110). Measured Pb/Pt and U/Pt abundance ratios are examined for information on a possible r-process, on solar system abundances, and on the time and time scale of the related nucleosynthesis events. The resolution of the experiment is deemed adequate to rule out the presence of superheavy nuclei. Experimental procedures, statistical treatment, and correlation with balloon data are discussed.
