Abstract
The angular anisotropy of Auger electrons from cascade Auger transitions in duced by photoexcitation of the 3d(5/2)(-1)5p resonance in Kr is reported. In contrast to the previously reported measurements for Ne and Ar, a large anisotropy is observed for the first-step spectator transitions 3d(5/2)(-1) 5p --> 4s(-1)4p(-1)5p and 3d(5/2)(-1)5p --> 4s(-2)5p while the second-step participator transitions are almost isotropic. These findings are qualitati vely explained by consideration of the alignment transfer via the first-ste p spectator Auger transitions.
