The following nuclear databases can be downloaded here.

• Evaluated Nuclear Structure Data File (ENSDF)
• Nuclear Science Reference File (NSR)
• Table of Radioactive Isotopes (TORI)

ENSDF - Evaluated Nuclear Structure Data File. A computer file of evaluated experimental nuclear structure data maintained by the National Nuclear Data Center, Brookhaven National Laboratory. For more information, click here.

• ENSDF Manual (PDF): The ENSDF database is a text file composed of independent datasets organized by mass number (A) and element (Z). For each isotope (AZ) there is an Adopted Dataset containing recommended level and gamma properties. Additional datasets for radioactive decay and reactions populating the isotope are also provided (670 KB).

• ENSDF Database: Self-extracting ENSDF archive (23 MB). Last updated March, 2006.

• XUNDL Database: Self-extracting ENSDF archive (2.3 MB). XUNDL contains nuclear structure and decay data compiled mainly from preprints or published journal articles. In some cases, the data were not published due to page limitations. The XUNDL file is maintained by the National Nuclear Data Center. Contact David Winchell ( Winchell@bnlnd2.dne.bnl.gov) or Balraj Singh (Balraj@MCMASTER.CA) for additional information. Last updated March, 2006.

• ENSDF Server: Internet access to ENSDF and XUNDL by A, AZ, and dataset.

• Isotope Explorer: Free software to display nuclear structure and decay data from the ENSDF database.
  1. VuENSDF 1.0 for Windows 3.1.
  2. Isotope Explorer 2.2 for Windows (95/98/NT/2000), Users Manual.
     
  3. Isotope Explorer 3.0 - ENSDF . Internet display of ENSDF data.
     
  4. Isotope Explorer 3.0 - XUNDL . Internet display of XUNDL data.

• NSR Manual (PDF): Coding manual for NSR (140 KB).

• NSR Database: Self-extracting NSR archive (24 MB). Files are provided for each year beginning with 1910. Last updated June, 2006.

• Nuclear Science Reference Search: Internet search of over 160,000 references from the NSR reference file by author, nuclide, reaction, keyword, and other data types.

• TORI Database: ACCESS format database (17.5 MB). Last updated February, 1999.

• TORI Internet Server: Internet search of the TORI database.
