Current requirements for heavy element and actinide nuclear decay data - May 1984

The current world requirements for heavy element and actinide decay data are discussed with respect to a variety of reactor-related applications and environmental studies. The important nuclides and their decay parameters are reviewed in terms of the recommendations made at the Second Advisory Group Meeting on Transactinium Isotope Nuclear Data, Cadarache, May 1979. Some of the accuracies requested in this earlier assessment are questionable, and specific requirements will prove extremely difficult to achieve. Nevertheless, certain improvements in the decay data are still required to assist in long-term storage calculations, non-destructive assays and L-x-ray studies. (author)
