Abstract: | In this paper, based on the exact Voigt profile we obtained, we derive the theory of resonance escape factors of plasma resonance
lines, for both Lorentzian profile and Voigt profile. The oscillator strength, the number density of the absorbing atoms in
the ground state, and the optical depth in the line center are discussed. As an example, the helium He I 1083.0 nm, lithium
Li I 670.970 nm and carbon C I 111.74 nm are discussed for infrared, visible and ultraviolet regions. The results we calculated
are in good agreement with the experimental results. These calculations will be significant in the theoretical analysis of
plasma.
