COMPREHENSIVE DATABASES WHY?

• maintenance of well-defined data archives for
  future generations
• interplay between nuclear reaction and decay data
  studies to define nuclear parameters to good
  accuracy
• significant impact of recommended data on
  developing nuclear theories
• assists in resolution of contradictory results
• identifies requirements and stimulates
  measurements
• benefits in applied areas - nuclear engineering,
  nuclear medicine, analytical and environmental
  sciences, etc.

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

12
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  physics databases will become hopelessly outdated

• So what happened in 2008?

OECD Global Science Forum Report of the Working
Group on Nuclear Physics, May 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.
15
OECD Global Science Forum Report of the Working
Group on Nuclear Physics, May 2008
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.

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

• 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

24
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
