Hi Daniel, Thanks - that does seem wrong. FWIW, Larch uses XrayDB which uses corehole widths from Krause and Oliver for Z>10 and Keski-Rahkoken nand Krause for Z<10. For the F K edge, this give 0.2089 eV. For this or other core-hole widths, and assuming you have Python installed, try: ~> pip install xraydb ~> python
import xraydb xraydb.core_width('F', 'K') 0.2089
Or install Larch and use ~> larch larch> core_width('F', 'K') 0.2089 On Mon, Sep 28, 2020 at 12:08 PM Daniel Przyrembel < daniel.przyrembel@fu-berlin.de> wrote:
To Whom it may concern,
I am quite sure there is a general lifetime/energy-width conversion error in Hephaestus: All core-hole lifetimes seem to come out too long by a factor of - as it seems exactly - 10: E.g. the lifetime of the F K-edge with a width of 0.25 eV is given as 25.30 fs instead of ca. 2.6 fs (width = h_bar / lifetime).
This glitch was present in 0.9.25 already and, as I noticed after updating, prevails in 0.9.26. I have not tried earlier versions.
Best regards,
Daniel
