In the present work it is shown that in atomic photoionization the Fano-like behaviour of vector correlation parameters in the region of an isolated autoionizing resonance possesses two universal values: the width and the energy shift with respect to the energy of the autoionizing state. This property is confirmed by fluorescence polarimetry studies, which provide, in the particular case of Xe 4d-15/26p(J = 1) photoexcitation, the experimental determination of the alignment and the orientation of the final photoion across the resonance.

Abstract
In the present work it is shown that in atomic photoionization the Fano-like behaviour of vector correlation parameters in the region of an isolated autoionizing resonance possesses two universal values: the width and the energy shift with respect to the energy of the autoionizing state. This property is confirmed by fluorescence polarimetry studies, which provide, in the particular case of Xe 4d-15/26p(J = 1) photoexcitation, the experimental determination of the alignment and the orientation of the final photoion across the resonance.File in questo prodotto:
