Electron energy loss spectra in the region below and above the Ne Is ionization threshold have been measured at several scattering angles between 2.4 degrees and 24.4 degrees and at a fixed scattered electron energy of 1.6 keV, while the impact energy has been scanned from 2.46 to 2.52 keV. Singly and doubly excited core states, corresponding to 1s --> nl and 1s2p --> nln'l' transitions, respectively, have been observed. The generalized oscillator strengths for both types of excitations have been derived from the angular variation of the double differential cross section and ab initio calculations have been performed using two methods based on a configuration-interaction approach.

Abstract
Electron energy loss spectra in the region below and above the Ne Is ionization threshold have been measured at several scattering angles between 2.4 degrees and 24.4 degrees and at a fixed scattered electron energy of 1.6 keV, while the impact energy has been scanned from 2.46 to 2.52 keV. Singly and doubly excited core states, corresponding to 1s --> nl and 1s2p --> nln'l' transitions, respectively, have been observed. The generalized oscillator strengths for both types of excitations have been derived from the angular variation of the double differential cross section and ab initio calculations have been performed using two methods based on a configuration-interaction approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
