Atomic Lithium Excitation by Electron Impact

Bethe approximation had been used to compute the excitation cross section in term of the diploe oscillator strength for some allowed transitions between energy levels of Li-atom collide with electrons with impact energy range (2-2000) eV. We also compute the radiation transition probability and lifetime. Our results for all calculations we had done were compared with the available theoretical and experimental data.
