Current status of nuclear decay data and report on the IAEA coordinated research programme on the measurement and evaluation of transactinium isotope nuclear decay data

In 1977, the IAEA organized a Coordinated Research Program (CRP) to address the needs for highly accurate actinide-nuclide decay data identified at the first Advisory Group Meeting on Transactinium Isotope Nuclear Data, held in Karlsruhe, FRG, in 1975. During the years of its existence, this CRP has made significant strides toward achieving the goals outlined at Karlsruhe and subsequently refined at a second Advisory Group Meeting held in Cadarache, France, in 1979. In this paper, the makeup of the CRP and its work in the areas of decay-data measurement and evaluation are presented and its significant accomplishments summarized. Also discussed are the contents and philosophy of the final report, including the results of the measurements and evaluations carried out by the CRP participants, to be published following the planned termination of this program in November 1984. 82 refs., 5 tabs
