Evaluation of Basic Properties of Nuclei: Updates on the AME and NUBASE

Understanding fundamental nuclear physics properties—such as masses, half-lives, isomers, excitation energies, spins, and decay branching ratios—is crucial for addressing key questions in nuclear physics and understanding the origins of elements in the universe. These properties are not only vital for nuclear physics research but also serve as essential inputs across various scientific domains, including atomic and high-energy physics, chemistry, and numerous practical applications. The demand for accurate and up-to-date nuclear data remains high, necessitating reliable evaluations for all known nuclei in both ground and excited, isomeric states.

The ongoing collaborative efforts in the Atomic Mass Evaluation (AME) and the evaluation of basic nuclear physics properties (NUBASE) involve scientists from China, Europe, and the USA. This presentation will offer insights into the methodologies and policies that guide the production of recommended nuclear data, along with updates on the content of the AME and NUBASE. Special focus will be placed on the role of evaluated data in enhancing our understanding of nuclei far from the line of stability, which are particularly significant for astrophysical applications.
