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. International Atomic Energy Agency

INTRODUCTION ENSDF Evaluated Nuclear Structure Data File organised multinational effort to maintain a comprehensive set of nuclear structure data files International Network of Nuclear Structure and Decay Data Evaluators (NSDD) – biennial meetings International Atomic Energy Agency

International Network of Nuclear Structure and Decay Data Evaluators (NSDD) • Collaborating multinational team of nuclear structure and decay data evaluators • Maintain and update ENSDF (Evaluated Nuclear Structure Data File) • Master database held at NNDC, BNL, USA • Individual regular communications • Biennial meetings held since 1974 under the auspices of the IAEA International Atomic Energy Agency

OECD Global Science Forum: Report of the Working Group on Nuclear Physics, May 2008 OECD (thirty Member countries): “…identify good practices and agree on decisions and action recommendations ………. Helping ensure development beyond OECD membership has been part of the Organisation’s mission from the start…” 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. International Atomic Energy Agency

Multinational mass chain evaluations Europe: What might be done? And do you want to do it? • contribute “at your weight” in carrying out mass chain evaluations for ENSDF (through the International Network of NSDD Evaluators) • establish a consortium of interested parties within an existing or new European Programme? • to be addressed by laboratories/institutes already involved in nuclear structure and decay data measurements International Atomic Energy Agency
