Raman regime energy dependence of alignment and orientation of KrII states populated by resonant Auger effect

The energy dependencies of alignment parameters A(20) for KrII 4p(4)5p states after the Auger decay of the KrI 3d(9)np resonances were investigated theoretically and experimentally for the first time in the Raman regime with the bandwidth of the exciting radiation (DeltaE(FWHM)=20 meV) smaller than the natural width of the resonances (Gammaapproximate to80 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 O-10 and the photoelectron angular distribution parameter beta(el) is also predicted.
