Resonance Escape Factor and Abundance of Plasma Li I Resonance Lines at 671nm

Article Preview

Abstract:

To study the spectrum of lithium plasma, the resonance escape factors of three resonance absorption lines that making up the LiⅠ671nm line are discussed theoretically, for both Lorentzian profile and Voigt profile. The number density of the absorbing atoms in the ground state, the oscillator strength, and the optical depth at the line center are also discussed in the calculation. The abundance of lithium relative to hydrogen is evaluated.The results we calculated are in good agreement with the experimental results. This calculation will be significant in the research of plasma lithium plasma.
