Abstract
The core electron satellite spectrum accompanying a 1s ionisation in atomic Ne is studied using monochromatised X-ray excited (1487 eV photon energy) photoelectron spectroscopy. Several new 2s-3s satellites are observed and assigned. The shake-off limits for the 2p-np and 2s-ns series are determined and also the continuum strength is measured to 37% of the main 1s line intensity. Fano-type resonances are detected both in the 2p-np and 2s-ns single shake-up regions and among the double shake-up lines. In the double shake-up region 18 lines are observed and a preliminary assignment is made using theoretical MCSCF calculations.Keywords
