Abstract
We show that the anisotropy of the photon excited Ar 2ns resonant Auger spectrum evolves smoothly into the anisotropy of the corresponding normal MM Auger spectrum as the excitation energy is tuned across the ionization threshold. Our results show that the difference between the angular anisotropy parameters of the resonant and normal Auger transitions becomes smaller than 10% around n≳14.
