The Auger decay process of the 3d5/2 hole is studied experimentally and theoretically along the isoelectronic Br, Kr⁺, and Rb2⁺ series with electron configuration [Ar] 3d⁹4s²4p⁶. The experimental results consist of multielectron coincidence data measured from all three elements and conventional high-resolution Auger spectrum for the Br case. Theoretical interpretation was done by using multiconfiguration Dirac-Fock calculations. It is found that the decay rate of two-Auger-electron emission increases along the series in the direction of decreasing nuclear charge. Also, complexity of the Auger spectrum follows the same trend, requiring a drastic increase to the size of the configuration space for describing the observed spectra.
