Final-state screening dynamics in resonant Auger decay at the 2p edge of vanadium
We investigated the resonant Auger process near the V 2p(3/2) edge in vanadium metal. Attention is centered on the onset of Auger decays and their behavior below the 2p(3/2) resonance. The 2p(3/2)3d3d decay has a crossover from the Raman-Auger to the normal Auger regime at the 2p ionization threshold. Meanwhile, Auger decays with core holes in the final state have normal Auger behavior even below the ionization threshold, the 2p(3/2)3p3p process being visible at 2.2 eV lower photon energy. The different resonant behavior of these Auger decays can be understood within the one-step model as final-state screening effects. affecting the photoexcitation.
