Presentation Transcript

  1. The aims and activities of the International Network of Nuclear Structure and Decay Data Evaluators Alan Nichols1 and Jagdish Tuli2 1 International Atomic Energy Agency, Vienna, Austria 2 National Nuclear Data Center, Brookhaven National Laboratory, USA [part of presentation at ND2007, International Conference on Nuclear Data for Science and Technology, 22-27 April 2007, Nice, France]

  2. Major impacts of NSDD ENSDF evaluations on nuclear physics • archive of all nuclear structure data for future generations • beneficial to many applied areas such as nuclear medicine, reactor engineering, activation analysis, environmental monitoring and impact assessments, etc. • encourages interplay between decay data and reaction data • beneficial consequences for developments in nuclear theory • resolves differences between overlapping and contradictory results • identifies needs for and stimulates new measurements

  3. ENSDF: Major Data Sources and Derivatives Contributing Databases: Atomic Masses (Wapstra & Audi) Nuclear Science References (NSR) • MC Codes • MCNPX • GEANT ENSDF NuDat2 IE ORTEC & CANBERRA Derivative Databases: … RIPL JANIS NUBASE MIRD RADWARE Derivative Publications:

  4. International Network Connections International Nuclear Structure and Decay Data Evaluators’ Network Long-Term Emerging New Contributors: Contributors: BELGIUM ARGENTINA CANADA AUSTRALIA CHINA BRAZIL FRANCE BULGARIA JAPAN INDIA KUWAIT RUSSIA7.3 FTE (US & Canada) USA2.2 FTE Total:9.5 FTE

  5. International Network Connections International Nuclear Structure and Decay Data Evaluators’ Network: responsible centres

  6. International Network Connections International Nuclear Structure and Decay Data Evaluators’ Network: responsible centres Total of ~ 9.5 FTE per annum “12 FTE per annum required to keep ENSDF in reasonably good shape” as quoted from INDC(NDS)-0476, Coordination of the International Network of Nuclear Structure and Decay Data Evaluators, Summary Report of an IAEA Technical Meeting, 6-10 June 2005, McMaster University, Hamilton, Canada (by Jagdish Tuli (NNDC))

  7. Multinational mass chain evaluations for ENSDF: numbers of responsible laboratories/institutes

  8. Multinational mass chain evaluations for ENSDF: numbers of responsible laboratories/institutes 1981: Europe BELGIUM FRANCE FRG NETHERLANDS SWEDEN UK 2007: Europe BELGIUM * FRANCE*

  9. Challenge Long-Term Contributors: BELGIUM * CANADA * CHINA FRANCE * JAPAN * KUWAIT RUSSIA USA * IAEA/ICTP NSDD training workshops have achieved some success Compilation and evaluation work is a useful service to the research community. We would like to ask you for your help and support. If we don’t act today, it may be too late tomorrow! NEW MASS CHAIN EVALUATORS REQUIRED NOW !!!YOUR COUNTRY (AND ENSDF) NEEDS YOU !!! - contact JK Tuli (NNDC, BNL) ~60% of the evaluators are close to retirement age (or beyond!)
