Ejected electron of atomic Cs have been measured at the 4d excitation resonances and above the ionization threshold using monochromatized synchrotron radiation. The spectra have been analyzed by comparing with the MCDF energy calculations and with previous experimental results. The resonance states were found to decay prominently via spectator Auger decay accompanied by transitions where the spectator electron shakes up during the decay. In the normal Auger electron spectra the shakeup structures mainly originate from the shakeup transitions accompanying the primary photoionization. Configuration interaction plays an important role in the spectra as well.

Abstract
Ejected electron of atomic Cs have been measured at the 4d excitation resonances and above the ionization threshold using monochromatized synchrotron radiation. The spectra have been analyzed by comparing with the MCDF energy calculations and with previous experimental results. The resonance states were found to decay prominently via spectator Auger decay accompanied by transitions where the spectator electron shakes up during the decay. In the normal Auger electron spectra the shakeup structures mainly originate from the shakeup transitions accompanying the primary photoionization. Configuration interaction plays an important role in the spectra as well.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
