Experimental Unevaluated Data (XUNDL)
Last updated 2013-02-06
The ENSDF database contains evaluated nuclear structure and decay information for over 3000 nuclides.
Continuously updated with new evaluations published in Nuclear Data Sheets.


Browse datasets by element or mass or search the ENSDF indices.
For more detailed search criteria, select items from the following tabs.
Retrieve all ENSDF datasets for a given nuclide or mass: (208Pb, pb-208, 144, etc.)
Dataset types:
  • Adopted
  • Decay
  • Reaction
  • Comments
  • Reference
Nuclide Z range: (56, 80-82, 102-, Ca, zr-mo, -Na, ...)
Nuclide A range: (56, 120-130, 208-, ...)
Nuclide: (58Ni, pb-208, ...)
Use this form to retrieve datasets based on reaction-related quantities. Non-blank criteria will be "anded" together to filter the datasets. The "Z range" and "A range" quantities refer to the nuclides for which datasets will be retrieved.

Indexed reaction values : (non-blank fields will be "anded")
