Phys. Rev. A 70, 032714 (2004) [5 pages]Generalized oscillator strengths for inner-shell electron transitionsReceived 26 January 2004; published 27 September 2004 A second-quantization formalism has been used to obtain a general expression for the generalized oscillator strength (GOS) for inner-shell electron transitions between two open shells of any atom. The present formula together with the spin polarized technique of the random-phase approximation with exchange are then employed to investigate correlation effects in the GOS for the Na 2p63s(2S)→2p53s2(2P) transition. Results are compared with those measured by Bielschowsky et al. Phys. Rev. A 43 5975 (1991). The present formula has also been used with Hartree-Fock wave functions to calculate the GOS’s for the carbon 2s22p2(3P)→2s2p3(3P) and 2s22p2(3P)→2s2p3(3D) transitions. The calculated multiplet oscillator strengths for the two transitions are compared with the experimental values. © 2004 The American Physical Society URL:
