[forensic-science] X-ray powder diffraction of an unknown substance


Dear Colleagues,
An off-topic question:
I would like to ask for your assistance in identifying an unknown substance
by its x-ray powder diffraction.
The substance is a yellowish powder, and its elemental composition is
mainly lead (Pb), maybe with some sulfur (S).
The diffractogram peak list is attached, as an Excel file.
Can anyone identify this substance ?
Any assistance will be acknowledged.
Thanks in advance, and best regards,
Nadav Levin
