Mass Chain Evaluations for the Evaluated Nuclear Structure Data File (ENSDF) – An Urgent Appeal for European Participation

F.G. Kondev, A.L. Nichols and J.K. Tuli


Nuclear Physics NewsNuclear Physics NewsEvidence 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


Nuclear Physics NewsNuclear 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of dedicated participants will fade away and as a consequence the core nuclear physics databases will become hopelessly outdated


So what happened in

2008?


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.

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.

• 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

Technical Meeting on “Reference Data Librariesfor Nuclear Applications – ENSDF”

10-11 November 2008, IAEA Headquarters,Vienna, Austria

Summary report prepared by Dimiter Balabanski and Alan Nichols, INDC(NDS)-0543,

reports/indc-nds/indc-nds-0543.pdf


Europe and ENSDFEurope and ENSDFConclusions, 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



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



Crash course – workshop:
