Atomic Masses, Q-values, and Threshold Energies
2003 atomic mass evaluation, NUBASE, PC-NUCLEUS. The program QCALC has been produced by the National Nuclear Data Center of the Brookhaven National Laboratory, Upton, NY, USA, with funding from the U.S. Department of Energy. The accompanying data base was produced by the Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse, Orsay Campus, France and the National Institute of Nuclear Physics and High-Energy Physics, Amsterdam, The Netherlands.
