International Atomic Energy Agency Nuclear Physics News Evidence of a shortfall in effort has been detected over the previous ten years as (ENSDF) evaluators in Europe have retired without any obvious replacements Although some progress has been made in recruitment through the commitment of nuclear physics institutes in India and elsewhere for this essential work, these welcome additions are not commensurate with the losses experienced in Europe, a region of the world that might have been expected to ensure some re- generation of expertise in this vital area of research and development
International Atomic Energy Agency Nuclear Physics News The survival and maintenance of the quality of ENSDF depends on the recruitment of new data evaluators to replace the ageing nuclear physicists undertaking this important work Unless new blood can be introduced soon, there is a serious danger that the current loose confederation of dedicated participants will fade away and as a consequence the core nuclear physics databases will become hopelessly outdated
International Atomic Energy Agency So what happened in 2008?
International Atomic Energy Agency page 4: Success in basic research and its applications relies on systematic, accurate measurements and accumulation of nuclear data in certified, reliable databases. In some areas, such as nuclear energy, there is strong international coordination through agencies such as the OECD Nuclear Energy Agency, the IAEA, and the US Nuclear Data Program. However, the Working Group finds that gaps exist in the international plans for the coordination and oversight of these databases, and that available resources are insufficient. OECD Global Science Forum: Report of the Working Group on Nuclear Physics, May 2008
International Atomic Energy Agency page 4, Recommendation: The national agencies should work together with international organisations, such as the OECD Nuclear Energy Agency, The International Atomic Energy Agency, and the international science community, to create a more comprehensive international plan to acquire and curate nuclear data for the wider community. OECD Global Science Forum: Report of the Working Group on Nuclear Physics, May 2008
International Atomic Energy Agency Europe and ENSDF Technical Meeting on Reference Data Libraries for Nuclear Applications – ENSDF 10-11 November 2008, IAEA Headquarters, Vienna, Austria review and discuss possible new European input to the ENSDF database inputs are comprehensive mass-chain evaluations that constitute updated recommendations for the nuclear structure and decay data of nuclides assembled on the basis of mass number

Europe and ENSDF Definitions: Compilation: systematic collection and transcription of information on a given subject with collation and re- organization for optimal presentation to the users Evaluation: critical appraisal of all available information on a given subject and derivation of consistent best or preferred values with their uncertainties Mass chain: pertaining to properties of nuclides with a given mass number Selected/horizontal: pertaining to a particular nuclear property or properties for a range of nuclides

International Atomic Energy Agency Europe and ENSDF Technical Meeting on Reference Data Libraries for Nuclear Applications – ENSDF 10-11 November 2008, IAEA Headquarters, Vienna, Austria Summary report prepared by Dimiter Balabanski and Alan Nichols, INDC(NDS)-0543, available from http://www-nds.iaea.org/reports-new/indc- reports/indc-nds/indc-nds-0543.pdf
International Atomic Energy Agency Europe and ENSDF Conclusions, 11 November 2008 1.Nuclear structure and decay data specialists within Europe assembled for two days at IAEA Headquarters in Vienna to determine interest and willingness to undertake mass-chain evaluations for ENSDF 2.Much interest and commitment was expressed in such work 3.Inevitably, financial support is the major issue – NuPNET is seen as an appropriate vehicle for aligning and generating national support for this type of evaluation effort 4.The International Network of Nuclear Structure and Decay Data Evaluators is scheduled to meet at IAEA Headquarters from 23 to 27 March 2009 for its biennial meeting, and arrangements have been made for committed European nuclear structure experts to attend 5.A one-week training course in ENSDF evaluation procedures needs to be held in the near future, and preparative discussion should begin immediately
International Atomic Energy Agency Europe and ENSDF ACTIONS, 11 November 2008: Dimiter Balabanski and Christoph Scheidenberger – explore and quantify European interest in and viability of forming a European collaborative effort to support ENSDF through the contribution of regular mass-chain and horizontal evaluations IAEA and NNDC staff – assess feasibility of one- week workshop within Europe for would-be mass-chain evaluators already possessing nuclear structure expertise
