[en] This report presents the status of nuclear structure, decay data, and related activities of the National Nuclear Data Center (NNDC) for the period December 2003 to May 2005. It describes the ENSDF evaluation activity and reviews, evaluation processing and priorities, nuclear wallet cards, nuclear science references, the ENSDF software and hardware environment and the web-based services

[en] The Table is now current to late 2004. Currently the prime objective, in addition to keeping the Table up-to-date, is to survey all measurements and give recommended values. To this end a set of interrelated standard values for several reference moments is being set up. Ways in which re-assessment of data may help to resolve the incompatibilities mentioned above are being explored and this is keeping further determination of recommended values on hold for the immediate future

[en] This report describes the activities of the Lawrence Berkeley National Laboratory for November 2003 to May 2005. Their mass chain evaluation responsibilities are A = 21-30, 59, 81, 83, 90-93, 166-171, 210-240 (∼520 nuclides, since Nov. 2004). The nuclear structure and decay evaluations and the constrained statistical model (COSMO) calculations are described. Research activities and nuclear structure data dissemination are outlined. A list of nuclear data related publications is given

[en] The IAEA Nuclear Data Section convened the 16th meeting of the International Network of Nuclear Structure and Decay Data Evaluators at the Department of Physics and Astronomy, McMaster University, Hamilton, Canada, 6-10 June 2005. This meeting was attended by 33 scientists from 12 Member States concerned with the compilation, evaluation and dissemination of nuclear structure and decay data. A summary of the meeting, recommendations/conclusions, data centre reports, and various proposals considered, modified and agreed by the participants are contained within this document. (author)

[en] Brief summaries are given of the various tasks within the atomic and nuclear data subprogramme of the IAEA Nuclear Data Section that are judged to be of interest to the NSDD Network: Data services, data networks and user support; Nuclear data standards and evaluation methods; Nuclear data for radiotherapy using radioisotopes and external radiation sources; Data for Th-U fuel cycle; Nuclear data for reactor dosimetry and analysis and for advanced nuclear facilities

[en] Full text: This report covers the evaluation activities of the Kuwaiti Group for the period (May 2003 - May 2005). Mass Chain Evaluation: - A=74: Ameenah Farhan worked on this mass chain in collaboration with Dr. Balraj Singh, submitted May 2005. - A=78: Work is currently in progress on this mass chain. It will be completed and submitted by the end of summer 2005. Personnel: - Ameenah Farhan is working as a part-time researcher for the center (0.2 FTE); - Prof. Ashok Jain, will be joining the Physics Department as a visiting professor for one year, starting September 2005. He will have a role in the data evaluation activities of the center. - The Kuwait Group will continue its fruitful collaboration with Dr. Balraj Singh in order to fulfill its commitments. Financial Support: The research activities of the Kuwait Nuclear Data Center are funded by Kuwait University Research Administration. (author)

[en] We discuss here the meaning of discrepant data sets from an information point of view. Reduction of these data sets can be achieved by a Bootstrap Method to obtain parameters that behave like the usual mean and standard deviations. The Bootstrap Method is also useful to define a safe bound for the standard deviation calculated by practical methods. (author)

[en] The Argonne Nuclear Data Program includes a variety of scientific activities carried out within the broader framework of the Coordinated Work Plan of the U.S. Nuclear Data Program. Among these are the compilation and evaluation of nuclear structure and nuclear reaction data, and the development of nuclear data measurement, analysis, modeling, and evaluation methodologies for use in basic science and technology applications. Contributions are also made to various specialized databases serving specific needs in the fields of nuclear structure, nuclear astrophysics, and applied nuclear physics. The main program activities are nuclear structure and decay data evaluations for ENSDF and specialized decay data evaluation for DDEP

[en] Evaluation work at the Indian Institute of Technology, Roorkee started about 2 years ago. At present this work is being carried out in collaboration with Balraj Singh (McMaster University), who is also the primary mentor of the NSDD evaluation programme in India. The following progress has been made: The A=165 mass chain is complete and ready for submission. From the previous evaluation, which was about 8000 lines, this mass chain evaluation has grown to almost 16000 lines. The A=218 mass chain evaluation has made good progress. We hope to complete and submit by the end of June 2005. Several workers from India have participated in the ICTP Training Workshops held at Trieste. They have shown considerable interest. Roorkee has a good infrastructure and may be ready for the status of a full NSDD Evaluation Centre - would also be able to coordinate the activities of other scientists interested in evaluation work and based in India
