The AME2020 atomic mass evaluation

This is the second part of the new evaluation of atomic masses, AME2020. Using least-squares adjustments to all evaluated and accepted experimental data, described in Part I, we derived tables with numerical values and graphs which supersede those given in AME2016. The first table presents the recommended atomic mass values and their uncertainties. It is followed by a table of the influences of data on primary nuclides, a table of various reaction and decay energies, and finally, a series of graphs of separation and decay energies. The last section of this paper provides all input data references that were used in the AME2020 and the NUBASE2020 evaluations.

Automated summary

The second part of the new evaluation of atomic masses, AME2020, introduces tables and graphs derived through least-squares adjustments to experimental data. The paper concludes with a section providing references for all input data used in the AME2020 and NUBASE2020 evaluations.
