Abstract

The triple ionization spectrum of atomic Cd formed upon the removal of a $4 p$ or a $4 s$ inner-shell electron and subsequent Auger decays has been obtained at 200 eV photon energy. By using a versatile multielectron coincidence detection technique based on a magnetic bottle spectrometer in combination with multiconfiguration Dirac-Fock calculations, Auger cascades leading to tricationic final states have been analyzed and final-state configurations have been identified. The most prominent Auger cascades leading to the ground state of ${Cd}^{3 +}$ have been identified in good agreement with theory.
