Hi, The documentation for Hephaestus lists the same paper as you indicated. (Access by going to Help-Document in Heph.) Another reference with values tabulated is: http://aip.scitation.org/doi/10.1063/1.555595 Natural widths of atomic K and L levels, Kα X‐ray lines and several KLL Auger lines Journal of Physical and Chemical Reference Data 8, 329 (1979); M. O. Krause and J. H. Oliver But I have noticed the values differ between that work and those in Heph/earlier work. Krause and Oliver did not even cite that earlier work. -R.

Dear All
This might be a stupid question, but I have not been able to track this down myself:
What is the data source of the "core-hole lifetimes" (i.e. the energy widths "gamma(ch)" in eV) of the "Absorption edges" in the "Absorption" panel of Hephaestus?
As far as I could see these lifetimes/widths are not given in the 'Elam database'. Other XAS data tools based on the Elam database (like e.g. 'XrayDB') claim to be using values from 'O. Keski-Rahkonen and M. O. Krause, Atomic Data and Nuclear Data Tables 14, pp139-146 (1974) (http://dx.doi.org/10.1016/S0092-640X(74)80020-3)' for this. Because that reference does not give tabulated values but rough data plots only, it is difficult to compare those with the values in Hephaestus.
If someone knows the respective data source used in Hephaestus, the answer/information is deeply appreciated!
Best regards
Daniel
