Double electron transitions [MN] or [MO] above 74W MIII edge in X-ray absorption spectra.
The x-ray absorption spectra in metallic W (Tungsten) have been measured above MIII edge using the third generation synchrotron radiation. ALS, Berkeley. Several features caused by multi-electron transitions were detected on MIII in solid phase. [3p4f], [3p5s], and [3p5p] double electron transitions were identified by the Z+1 approximation.
