The Atomic Mass Evaluation (AME) provides the most reliable source for values of atomic masses and their uncertainties. The AME considers all experimental data related to atomic masses extracted from the available literature. They are compiled in an appropriate format and then carefully examined. A least-squares fit method is used to determine the best values for the atomic masses and to quantify their uncertainties. The atomic mass table, main product of the AME, is used as the source of the reference values in all mass model development and all mass measurement experiments.
The Nubase evaluation combine all basic properties fo nuclei in their ground and isomeric states in a consistent way, and in full coordination with the AME.
Because of their wide applications, the AME+NUBASE evaluations are the most cited works in the research field of nuclear physics.
