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:
Natural widths of atomic K and L levels, Kα X‐ray lines and several KLL
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
Krause and Oliver did not even cite that earlier work.
