Abstract:
This paper is the first of two articles (Part I and Part II) that presents the results of the new atomic mass evaluation,
AME2012. It includes complete information on the experimental input data (including not used and rejected ones), as well as
details on the evaluation procedures used to derive the tables with recommended values given in the second part. This article
describes the evaluation philosophy and procedures that were implemented in the selection of specific nuclear reaction, decay
and mass-spectrometer results. These input values were entered in the least-squares adjustment procedure for determining
the best values for the atomic masses and their uncertainties. Calculation procedures and particularities of the AME are then
described. All accepted and rejected data, including outweighed ones, are presented in a tabular format and compared with
the adjusted values (obtained using the adjustment procedure). Differences with the previous AME2003 evaluation are also
discussed and specific information is presented for several cases that may be of interest to various AME users. The second
AME2012 article, the last one in this issue, gives a table with recommended values of atomic masses, as well as tables and
graphs of derived quantities, along with the list of references used in both this AME2012 evaluation and the NUBASE2012
one (the first paper in this issue).
