Experimental studies to improve specific actinide decay data

A Co-ordinated Research Project (CRP) entitled "Updated Decay Data Library for Actinides" was initiated in 2005 by the International Atomic Energy Agency (IAEA), with the primary aim of improving the quality of recommended decay data for actinides and their decay chains. Participants have attended two Research Coordination Meetings, and agreed on a list of important nuclides and evaluation methodologies to be adopted in work programmes dedicated to the preparation of a new database. Specific measurements were also proposed to address discrepancies between existing data, and some of these experimental studies are described in detail within this paper.
