Abstract
TheKLL-Auger spectrum of neon was investigated with an electrostatic spectrometer with an energy resolution of 0.12%. The ionization in theK-shell was caused by electron impact. The use of a gaseous target made it possible to measure the Auger electrons without any energy loss. The relative intensities of the KLL-lines were determined to be:KL 1 L 1(1 S 0)=1.0;KL 1 L 2,3(1 P 1)=3.06±0.07;KL 1 L 2,3(3 P 0,1,2)=0.98±0.05;KL 2,3 L 2,3(1 S 0)=1.67±0.08;KL 2,3 L 2,3(1 D 2)=13.1±0.6;KL 2,3 L 2,3(2 P 0,2)=0. This is in agreement with an earlier measurement byKörber andMehlhorn but disagrees with all theoretical values calculated nonrelativistically for low Z. It is shown that agreement may be achieved by applying quantitatively the configuration interaction, introduced very recently byAsaad, and using improved wave functions for the calculation of the transition amplitudes.
As a consequence of the ionization by electron impact also theKL-LLL Auger spectrum was caused. 10 lines of this spectrum were measured and identified.
Moreover, from the Auger energies measured, the binding energyE(K) of neon was calculated to be E(K)=(870.0±0.4) eV.
