NA 14 (AAME)Advanced Atomic Mass Evaluation

• Collect and evaluate experimental data on atomic masses (Q-values, excitation energies, lifetimes, etc.). Continuation of and improving the Atomic Mass Evaluation.

• Maintaining the existing (e.g. Nucleus) and developing new tools (mass calculators, filters, extrapolations, etc.).

• Creating and sustaining databases for experimental and theoretical data.

• Coordinating the information flow between different experimental and theoretical groups. (efficient coordination)

• Creating and/or maintaining the information exchange with other evaluation groups (NNDC, NuBASE, BrusLIB, etc.)

• Creation of a virtual journal on mass spectrometry for nuclear structure and astrophysics communities. (JRA10, Theory JRA)

• Organization of annual workshops and meetings (ECT*)
