ENSDF: its structure, contents, and use in applied research

A computer-based system for obtaining the energies and intensities of both nuclear and subsequent atomic radiations from radioactive nuclides in a format suitable for direct use by researchers in medical practice or research, health physics, industry, nuclear power, and environmental impact studies is discussed. The Evaluated Nuclear Structure Data File (ENSDF) consists of a set of evaluated data sets for each mass chain, including adopted level and decay schemes for each nuclide in that mass chain, and is prepared by the Nuclear Data Project at ORNL. The contents, organization, and status of ENSDF are described, along with its search and retrieval capabilities; both tabular listings and graphical displays may be produced. 3 figures. (RWR
