英文摘要	High-energy electron-impact excitation cross sections are directly proportional to the generalized oscillator strengths (GOS's) of the target (an atom or molecule). In the present work, the GOS's for the Na 3s-3p and 2p-3s transitions are calculated by using the updated R-matrix codes. The present results for the 3s-3p transition are in good agreement with the experimental measurements at 1 keV incident energy. For the 2p-3s resonance transition, the present results are larger than the measurements at 1 keV incident energy. The difference is discussed. The important role of the inner shell electron correlations is elucidated. The positions of the first and second GOS minimums and maximums for these two transitions are reported. The dependence of the GOS minimum and maximum positions on the increasing incident energies are discussed.; Optics; Physics, Atomic, Molecular & Chemical; SCI(E); EI; 4; ARTICLE; 5; 78
