Abstract

Recent measurements with radioactive beams at ORNL's Holifield Radioactive Ion Beam Facility (HRIBF) have prompted evaluations of the structure and reactions of unstable nuclei that play an important role in stellar explosions. The evaluation work focuses on reactions involving unstable nuclei and their associated level structures. To determine the astrophysical impact of these evaluations and other new nuclear physics results, it is vital to rapidly and accurately process and incorporate them into astrophysics models. We discuss the development of a new computational infrastructure that streamlines this process, and is available online at nucastrodata.org. This site also hyperlinks all available nuclear data sets relevant for nuclear astrophysics studies. Features of the suite and future developments are described. © 2005 American Institute of Physics.
