[en] The Japanese NSDD group is responsible for mass chain evaluations of A=120-129. We are now evaluating A=120, 123 and 126. Both A=120 and 126 have almost been completed, and first drafts will be sent to NNDC within a few months for review. Also, the references for A=122 and 124 are now being collected in order to start the evaluation of these mass chains.

[en] An NSDD Data Centre was established in IFIN-HH, Bucharest with the approval of the network meeting that took place in Vienna, May 2015. Two evaluators are involved in this activity, each of them dedicating 0.2 FTE to evaluation (total of 0.4 FTE). This level of activity is supported by IFIN-HH. A Research Contract proposal was submitted for funding to IAEA-NDS, and a positive reply was recently received.

[en] Nuclear Data activities under the Nuclear Data Group of LBNL+UCB (earlier known as the Isotopes Project at LBNL) cover nuclear structure data evaluation, experiments and evaluation of neutroncapture gamma-ray data for Evaluated Gamma-ray Activation File (EGAF), and nuclear reaction studies for applied applications using neutrons from local facilities, like deuteron break-up reaction at 88-inch cyclotron at LBNL and DD neutron generator at the University of California at Berkeley (UCB) and other facilities such as the nuclear research reactors at Budapest, Hungary and FRM, Germany, and the cyclotron facility at the University of Oslo all through international collaboration. An organised Nuclear Data Needs and Capabilities for Applications (NDNCA) workshop led to the production of a white paper.

[en] NSCL/MSU became a data center member of the NSDD network at the 2015 IAEA NSDD meeting in Vienna, and plays a unique role as part of the FRIB/NSCL facilities. NSCL/MSU took over responsibility for the evaluation of fourteen mass chains (A = 31-44), and also compiles data for the XUNDL database, including all future data coming from NSCL and FRIB. The centre is also helping to develop and improve the analysis and utility tools used in data compilation and evaluation.

[en] The 22^nd meeting of the International Network of Nuclear Structure and Decay Data Evaluators was convened at the Lawrence Berkeley National Laboratory, Berkeley, USA, from 22 to 26 May 2017 under the auspices of the IAEA Nuclear Data Section. This meeting was attended by 38 scientists from 12 Member States and the IAEA, all of whom are concerned primarily with the measurement, evaluation and dissemination of nuclear structure and decay data. A summary of the meeting, data centre reports, various proposals considered, technical discussions, actions agreed by the participants, and the resulting recommendations/conclusions are presented within this document.

[en] The Argonne Nuclear Data Program is identified with a number of scientific activities carried out within the broad framework of the US Nuclear Data Program (USNDP) Coordinated Work Plan. Emphasis is placed on nuclear structure and decay data, and their applications in nuclear physics research, and in applied nuclear technologies. Compiled and evaluated data are made available to the National Nuclear Data Center (NNDC) for inclusion in the Evaluated Nuclear Structure Data File (ENSDF) database, or results are published directly in peer-reviewed scientific journals. Contributions are also made to various specialized databases that serve specific needs in the fields of nuclear structure, nuclear astrophysics and applied nuclear physics. This effort includes the evaluation of atomic masses and complementary nuclear structure data for the Atomic Mass Evaluation (AME) and NUBASE databases, and compilations of recently published nuclear structure data for the XUNDL database (Unevaluated Nuclear Data List). Measurements aimed at providing answers to specific questions and improving the quality of existing databases in specific areas are also performed. Experiments are carried out at the US Department of Energy nuclear physics user facilities and at leading nuclear physics laboratories elsewhere through collaborative arrangements.

[en] The NNDC is the sole contributor to NSR compilations, and the only US contributor to EXFOR with ~ 4000 articles per year for the former and ~ 200 datasets per year for the latter. NNDC also contributes a large number of XUNDL compilations every year. NNDC contributed 214 ENSDF evaluations in FY2015 and 137 in FY2016. We have also taken a very active role in the revision of ENSDF policies and guidelines, as well as the implementation of the JAVA-NDS code to replace Webtrend (old Nuclear Data Sheets publications code). A number of format extensions are now being considered. The NNDC maintains a comprehensive web site powered by five high-end servers, which disseminate a number of databases in both their basic formats as well as user-friendly outputs. We are currently experiencing about 4 million database retrievals per year. NNDC continues to publish the Nuclear Data Sheets journal, with an output consisting of mass-chain evaluations and specialized nuclear data articles. Every year we organize a Nuclear Data Week in early November. This event consists of several well-organized group discussions, including the annual meetings of the USNDP and CSEWG and (since 2015) the US Nuclear Data Advisory Committee meeting. The NNDC has active research programs, as evidenced by a number of recent high-profile publications: (a) measurement of precise decay radiation for isotopes of medical interest; (b) understanding of the physics underlying the antineutrino emissions from nuclear reactors; (c) structure of light and heavy nuclides. NNDC staff are also active participants in the IAEA coordinated research project on “Development of reference database for beta-delayed neutron emission”, as well as B(E2) evaluations.

[en] TUNL is responsible for data evaluations in the mass range A = 3-20. Since the last IAEA NSDD meeting a review of A=12 nuclides has been completed, and a review of A=3 nuclides, based on our 2010 Nuclear Physics article, was published in NDS. A review of A=2 nuclides continues.
