摘要: The electron-energy-loss-spectrum of sodium has been measured in discrete region at a 1.5 keV impact energy and mean scattering angle 0°. relative optical oscillator strength density spectrum the valence shell was established by using dipole (e, e) method then normalized to theoretical 32S → 32P excitation. strengths 42P 52P excitations obtained present work are 0.014 ± 0.002 0.0026 0.0004, respectively. Theoretical values for n2P (n = 3 - 5) were relativistic configuration interaction method, which 0.97, 0.012, 0.0025,
