NA 14 (AAME)

1. NA 14 (AAME) Advanced Atomic Mass Evaluation

2. Purpose of AAME • 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*)

3. Why NA? Nuclear structure and astrophysics communities masses, Q, T1/2, E*, etc.. Experimental groups key nuclides to be measured AME, Tests of mass models, databases, tools etc., AAME New models Up-to date evaluation AME Theoretical groups Optimized and coherent use of data from research infrastructures for the benefit of physics community
