Abstract
The energy dependencies of alignment parameters A20 for Kr II 4p45p states after the Auger decay of the KrI 3d9np resonances were investigated theoretically and experimentally for the first time in the Raman regime with the bandwidth of the exciting radiation (ΔEFWHM=20 meV) smaller than the natural width of the resonances (Γ≈80 meV). The observed energy dependence is due to the interference between the different resonance channels and the direct photoionization channel. A strong energy dependence for both the orientation parameter O10 and the photoelectron angular distribution parameter βel is also predicted.
