Alignment of ions after autoionization decay of atomic resonances: II. The 3d⁹_5/25p (<i>J</i>= 1) resonance in Kr

Abstract

The alignment of Kr II 4p45p (EJ) states after the Auger decay of the Kr I 3d95/25p (J = 1) resonance was measured using photon-induced fluorescence spectroscopy (PIFS) and the alignment parameters A20 were calculated within the stepwise decay model. Using the same wavefunctions, the angular distribution parameters of the Auger electrons were also calculated. Good agreement with the measured A20 value and with published experimental and calculated values for βAug is obtained.
