Experimental Investigation of Optical Properties of Nonideal Plasma within the Electron Concentration Range 1017 cm3<Ne<1022 cm3
Annotation
The optical properties of nonideal plasmas within the electron concentration range 1017 cm3<Ne<1022 cm3 are studied experimentally. According to these results, as well as to the data available in the literature, we obtain the experimental dependence of the ΔE (the difference between the atom ionization potential and the excitation potential of the upper level of the last observed emission or absorption line) value on the electron concentration within the range taken. The dependence is compared to the earlier obtained theoretical formulas. Recommendations on application of the experimental formula to determine the electron concentration in the external layers of the non-ideal plasma at Ne<1022 cm3 are presented.
