Abstract

The giant-halo inclusion 19D reported to show the strongest evidence for superheavy elements on the basis of proton-induced x-ray fluorescence has been re-examined with ≈ 55 times greater sensitivity by employing synchrotron radiation as the exciting source. It is shown conclusively that at concentration levels of ≈ 5 × 108 atoms per inclusion, superheavy elements are not present in GH19D or in numerous other giant-halo inclusions studied.
