Phys. Rev. A 71, 032714 (2005) [5 pages]Selectivity in valence excitation processes of noble atoms studied by fast electron impactReceived 13 September 2004; published 21 March 2005 The experimental and theoretical ratios of the generalized oscillator strength (GOS) for valence excitations of Ne, Ar, and Kr are presented. The excitation selectivity for fast electron impact is elucidated: the LS coupling singlet nature of the ground state selects the LS coupling singlet components from the intermediate coupling wave function of the excited state. According to this rule, the GOS’s for some unresolved transitions were determined. Furthermore, this work provides an experimental method to determine the intermediate coupling coefficients of singlet components. © 2005 The American Physical Society URL:
