INTERNATIONAL NETWORK OF NUCLEAR STRUCTURE AND DECAY DATA EVALUATORS (NSDD)
Scientific Secretary: Paraskevi Demetriou
Meeting on XUNDL
A 1.5 day working group meeting is scheduled May 16-17 to discuss activities connected with XUNDL. The meetings will be held at the Triangle Universities Nuclear Laboratory starting 9:00 AM Thursday morning. A closeout session is planned for around midday Friday.
An initial list of topics to be discussed includes:
The meeting format is to remain loosely constrained to discussion of critical issues for XUNDL, rather than formal presentations. The organizer and contact person is John Kelley.
20th Meeting of the NSDD Network
The 20th IAEA meeting of the NSDD network was hosted by the Kuwait Foundation for the Advancement of Sciences (KFAS) and Physics Department-Kuwait University, in Kuwait, from 27-31 January 2013.
We gratefully acknowledge KFAS generous contribution towards the expenses of the meeting and the warm hospitality of the hosts during the meeting.
The NSDD Network
The International Network of Nuclear Structure and Decay Data (NSDD) is an international team of experts who provide recommended nuclear structure and decay data to be used in basic and applied research. These data include:
Evaluated nuclear quantities include the following: disintegration energies, radiation and transition probabilities, nuclear level schemes, excitation energies, half-lives, decay modes, spin-parity values, magnetic and electric multipole moments, and nuclear band structure. The NSDD network was established in 1974 under the auspices of the International Atomic Energy Agency (IAEA), and includes 18 data centres and groups located in laboratories, institutes and universities within 10 countries. Network scientists evaluate nuclear structure and decay data for all isotopes on an agreed basis; they also compile the most recent experimental results in the Unevaluated Nuclear Data Library (XUNDL). NSDD databases contain these data in computerised format and are available both online and offline. These evaluations are also published in the journals Nuclear Physics A and Nuclear Data Sheets. The NSDD Network welcomes participation from other groups interested in contributing to this activity.
Meetings of the International Network of Nuclear Structure and Decay Data Evaluators (NSDD) are coordinated by the IAEA, while staff at Brookhaven National Laboratory, USA, are responsible for both the technical and database issues. NSDD members meet biennially (once every two years) to discuss the current status of the mass chain evaluations, evaluation responsibilities, and processing code needs, as well as ENSDF formats. Priority activities for the subsequent two years are also agreed. These NSDD meetings are held alternatively at the data centres and IAEA Headquarters in Vienna.
The IAEA organizes jointly with the International Center for Theoretical Physics, Trieste, Italy, a workshop on "Nuclear Structure and Decay Data: Theory and Evaluation" in Miramare, Trieste, every second year. These workshops constitute a unique opportunity for scientists to gain extensive and up-to-date training on the evaluation of nuclear structure and decay data, as developed to produce the Evaluated Nuclear Structure Data File (ENSDF) and Nuclear Data Sheets for use and adoption by the nuclear physics community.
