Prediction of molecular auger rates using a statistical model

Total Auger rates for some nitrogen- and silicon-containing molecules have been calculated by two different methods. Using a direct approach, the rates for individual transitions have been calculated and then totalled. Alternatively, the total rate has been determined using a statistical approach based upon knowledge of the MuIIiken atomic orbital populations in the molecule and the atomic Auger subshell rates. There is good agreement between the two approaches. Total Auger rates based on the statistical approach enable a first estimate of some core-hole inherent lifetimes in molecules to be determined.
