Abstract:According to Stark broadening theory, Stark broadening spectral line profile is asymmetric in essence considering plasma ions impact. The electric microfield distribution function is very important for the spectral line profile. The Stark broadening spectral line profile is described with different electric microfield distribution functions. The results show that the Stark broadening spectral line profile is similar with the Holtsmark distribution and nearest-neighbor field distribution, and it is diversification with Mayer model. With the decrease in the electrons impact broadening parameter, the influence of different electric microfield distribution functions is diminished. With the decrease in the plasma ions impact parameter, the influence of different electric microfield distribution functions is trailing off. The results also show that the action of electric microfield distribution functions is similar when the plasma ions impact parameter is very small. It is illustrated that the intense impact of plasma ions has great influence on the spectral line profile. The results may have important reference for the plasma diagnosis.
