Auger-electron and x-ray production in 50- to 2000-keV Ne+Ne collisions
Journal Article

· Physical Review, A (General Physics)
The production of vacancies in the inner and outer shells of the target and projectile have been studied in Ne/subi/$sup +$+Ne collisions in the incident energy range of 45 keV to 2.2 MeV through the observation of K x rays and Auger electrons. Data are given for incident charge states i=0, 1, and 2. Parameters necessary for the analysis of collision kinematics were extracted from previous data and used to investigate these effects on the observed Auger spectra. The kinematic line broadening in the Ne collisions is shown to obscure the peak structure characteristic of the multiple ionization states. The centroid energies and average energy widths of the Auger groups, together with absolute intensities, are reported as a function of the Ne/subi/$sup +$ energy and electron emission angle for both target and projectile. Absolute cross sections for x-ray and Auger-electronproduction are reported with an accuracy of about plus-or-minus15%, and mean fluorescence yields are determined from these cross- section data. Information regarding the coupling of outer-shell molecular orbitals in the entrance channel is extracted from the comparison of the measured data and previous calculations.
