Please ask experts to help answer, why the NiO L2 edge data will split into two peaks in SXAS.
Dear Tao Zeng ,
please have a look at the discussion in the section
'In-situ X-ray absorption spectroscopy at the nickel and iron L- and K-edges'
at the bottom of page 3 (in the .pdf) about the split of the L3 and L2 edges of Ni:
