Abstract
The lifetimes due to Auger-electron emission for a hole on a deep electronic shell of neutral and charged sodium clusters are studied for different sizes. We consider spherical clusters and calculate the Auger-transition probabilities using the energy levels and wave functions calculated in the local-density approximation. We obtain that Auger emission processes are energetically not allowed for neutral and positively charged sodium clusters. In general, the Anger probabilities in small Na-N(-) clusters are remarkably different from the atomic ones and exhibit a rich size dependence. The Auger decay times of most of the cluster sizes studied are orders of magnitude larger than in atoms and might be comparable with typical fragmentation times. [S0163-1829(98)07107-0].
