This paper is the second part of the new evaluation of atomic masses, Ame2012. From the results of a least- squares calculation, described in Part I, for all accepted experimental data, we derive ...here tables and graphs to replace those of Ame2003. The first table lists atomic masses. It is followed by a table of the influences of data on primary nuclides, a table of separation energies and reaction energies, and finally, a series of graphs of separation and decay energies. The last section in this paper lists all references to the input data uaad in Part I of this Ame2012 and also to the data includad in the Nubase2012 evaluation (first paper in this issue).
This paper is the second part of the new evaluation of atomic masses
Ame2003. From the results of a least-squares calculation described in Part I for all accepted experimental data, we derive here ...tables and graphs to replace those of 1993. The first table lists atomic masses. It is followed by a table of the influences of data on primary nuclides, a table of separation energies and reaction energies, and finally, a series of graphs of separation and decay energies. The last section in this paper lists all references to the input data used in Part I of this
Ame2003 and also to the data entering the
Nubase2003 evaluation (first paper in this volume).

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 experinrental 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).
This paper presents the
Nubase evaluation of nuclear and decay properties of nuclides in their ground- and isomeric-states. All nuclides for which some experimental information is known are ...considered.
Nubase uses extensively the information given by the “Evaluated Nuclear Structure Data Files” and includes the masses from the “Atomic Mass Evaluation” (
Ame, second part of this issue). But it also includes information from recent literature and is meant to cover all experimental data along with their references. In case no experimental data is available, trends in the systematics of neighboring nuclides have been used, whenever possible, to derive estimated values (labeled in the database as non-experimental). Adopted procedures and policies are presented.

This paper is the first of two parts presenting the result of a new evaluation of atomic masses (
Ame2003). In this first part we give full information on the used and rejected input data and on the ...procedures used in deriving the tables in the second part. We first describe the philosophy and procedures used in selecting nuclear-reaction, decay, and mass spectrometric results as input values in a least-squares evaluation of best values for atomic masses. The calculation procedures and particularities of the
Ame are then described. All accepted data, and rejected ones with a reported precision still of interest, are presented in a table and compared there with the adjusted values. The differences with the earlier evaluation are briefly discussed and information is given of interest for the users of this
Ame. The second paper for the
Ame2003, last in this issue, gives a table of atomic masses, tables and graphs of derived quantities, and the list of references used in both this evaluation and the
Nubase2003 table (first paper in this issue).

This paper presents a complete list of “mass excesses”, which is an update of the similar values in the 1993 Atomic Mass Evaluation, and a list of the isomeric transition energies which are best ...determined from a combination of masses. A list of new or revised experimental data for mass determination is also given. The significance of these data, and their possible deviation from earlier ones or from expectations are discussed. Adopted new procedures and policies are presented.
The masses of 64 short-lived neutron-deficient nuclides covering the element range from tungsten to uranium have been obtained for the first time. They have been evaluated by combining directly ...measured masses from Schottky mass spectrometry with linked experimental
Q-values in
α-decay chains. Based on these new mass data we have determined the one-proton and two-proton drip-lines as well as the size of the “littoral shallow” of the sea of instability. No evidence of a Thomas–Ehrman shift has been found in the region of the investigated heavy nuclides. A peculiar behavior of two-proton separation energies has been observed in the lead region. The predictive power of various mass models is investigated.
