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
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 regeneration 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outdated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
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.
International Atomic Energy Agency
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.

Technical Meeting on “Reference Data Libraries
for Nuclear Applications – ENSDF”
10-11 November 2008, IAEA Headquarters,

• 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
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

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

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 oneweek workshop within Europe for would-be
mass-chain evaluators already possessing
nuclear structure expertise
