Evaluated Nuclear Structure Data File

The ENSDF database contains evaluated nuclear structure and decay information for over 2900 nuclides. The file is updated on a continuous basis. New evaluations are published in Nuclear Data Sheets. The database contains evaluated data for half-lives, properties of ground and excited states of all nuclides and their decay characteristics. The database is used for production of the journal "Nuclear Data Sheets" and different application oriented files and libraries.
IAEA Nuclear Data Section (NDS) coordinates the International Network of Nuclear Structure and Decay Data (NSDD)Evaluators by holding biennial meetings. NSDD evaluations for separate nuclides and mass chains of the nuclides prepared by the evaluators are introduced in the ENSDF database at the National Nuclear Data Center, BNL, USA for online access and published in the Nuclear Data Sheets journal .
