Abstract
We have studied, for the first time by electron spectroscopy, the Auger decay of the () resonances in ion. By detecting in coincidence the Auger electrons with the resulting ions, we unravel the contribution of the different final ionic states to the total cross section measured by ion spectroscopy. A strong intensity of satellite lines has been observed, up to 4 times stronger than the main lines. This unexpected behavior is confirmed by multiconfiguration Dirac-Fock calculations. This technique provides the most stringent test for theoretical models and allows us to disentangle the contribution of ions in the ground and metastable states in the target beam.
