Intra-atomic versus interatomic processes in resonant Auger spectra at theTi L-23 edges in rutile - art. no. 045110

The two components of the Ti L23M23V Auger transition recorded on a stoichi ometric rutile crystal are identified as L2M23V and L3M23V contributions. T his assignment is evidenced by concordant data relative to resonances of th e LMV decay at the Ti L-23 thresholds and to Auger emission recorded in coi ncidence with the 2(1/2) and 2(3/2) photoemission at a photon energy far ab ove the Ti L-23 edges. The L3M23V transition is shown to follow either the direct photoexcitation of a 2(3/2) electron or the fast Coster-Kronig decay of a 2(1/2) photohole. Although specific LMV contributions related to vale nce orbitals are identified, the long-suggested dual description of the L23 M23V Auger line as intra-atomic and interatomic transitions are discarded.
