This paper presents the Nubase2012 evaluation that contains the recommended values for nuclear and decay properties of nuclides in their ground and excited isomeric (T1/2≥100 ns) states. All nuclides for which some experimental information is known are considered. Nubase2012 covers all up to date experimental data published in primary (journal articles) and secondary (mainly laboratory reports and conference proceedings) references, together with the corresponding bibliographical information. During the development of Nubase2012, the data available in the "Evaluated Nuclear Structure Data File" (Ensdf) database were consulted, and critically assessed of their validity and completeness. Furthermore, a large amount of new and somewhat older experimental results that were missing in Ensdf were compiled, evaluated and included in Nubase2012. The atomic mass values were taken from the "Atomic Mass Evaluation" (Ame2012, second and third parts of the present issue). In cases where no experimental data were available for a particular nuclide, trends in the behavior of specific properties in neighboring nuclei (TNN) were examined. This approach allowed to estimate, whenever possible, values for a range of properties, and are labeled in Nubase2012 as "non-experimental" (flagged "#"). Evaluation procedures and policies that were used during the development of this database are presented, together with a detailed table of recommended values and their uncertainties.

This evaluation for A = 114 updates one by J. Blachot (2002Bl20), published in Nuclear Data Sheets 97, 593 (2002). Previous: 1995Bl09, 1990Bl05, 1982Bl18. Decay scheme of Tc-114 to Ru-114 seems incomplete. The decay scheme of 6.2-s isomer in I-114 seems very poorly known, and for the 2.1-s activity not well known either. None of these is published in a primary paper.

This evaluation for A=111 updates one by J. Blachot, (90Bl12), published inNuclear Data Sheets 60, 889(1990).Cutoff Date:All data available before October 1995 have been considered.General Policies and Organization of Material:See the January issue of Nuclear Data Sheets.General Comments:Throughout this evaluation, rotational band parameters have been calculated from the standard energy equation:[formula]The constant A reported in keV and the constant B, in eV. When “A” alone is given, “B” is assumed to be 0.Acknowledgments:Many useful comments and criticisms by the editors are greatly appreciated.

In December 2003, a full collection of atomic masses, AME 2003, was published, based on an evaluation of experimental masses. While evaluating the atomic masses it was found essential to create the NUBASE evaluation. We finally succeeded in having AME and NUBASE co-ordinated and published for the first time together.

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.Amdc: http://csnwww.in2p3.fr/AMDC/.

This paper presents the first version of the N 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. N has basically been derived from the “Evaluated Nuclear Structure Data Files” and from the “Atomic Mass Evaluation” of 1995, but it also includes information from recent literature or literature missed in one of these two evaluations and is meant to cover all experimental data along with their references. In case no experimental data is available, whenever possible, trends in the systematics of neighboring nuclides have been used to derive estimated values (labeled in the database as non-experimental). Adopted procedures and policies are presented.

Comprehensive decay-data and fission-yield libraries provide important input to a wide range of nuclear physics codes for nuclear applications. A new initiative has begun under the auspices of the NEA/OECD to generate improved data sets that will constitute the JEFF-3 libraries in ENDF-6 format, primarily for nuclear power, fuel reprocessing and waste management needs. Various sources of decay data have been accessed in order to assemble these files: NUBASE, ENSDF, UKPADD-6 and UKHEDD-2. Efforts have also focused on the evaluation of decay data for a number of important short-lived fission products, so that artificial adjustments to some of the relevant decay data and fission yields are not required to accommodate a previous lack of such data. Fission yields were adopted from UK evaluations recently undertaken to create the UKFY3 library. Decay-data files for 3 755 nuclides have been prepared, including sets of data for the stable nuclides (i.e. mass, natural abundance, spin and parity). Problems in the assignment of ENDF material numbers were addressed, while format and consistency tests were made using CHECKR and FIZCON, respectively. The assembly processes are discussed and reviewed, and the contents of the JEFF-3T starter libraries are described.
