We present an iterative kinetic model of the cathode-fall region in an abnormal glow
discharge of pure neon, which enables determination of the distribution of electric
field strength E, the distribution of the number densities of Ne atoms and Ne+ ions
together with the spectral shapes of Ne I and Ne II lines recorded end-on and side on at various distances from the cathode. We compare our model predictions with
corresponding experimental electric field strength distributions determined from Ne
I 515.443 nm line recorded side-on under same experimental conditions. These Ne I
line recordings enable experimental determination of the electric field distribution via
measurement of the Stark shift ∆λ and by using the Stark shift coefficient C in a well
known quadratic relation ∆λ = −λ
2CE; the value of C is reported in Ivanovi´c et al.
2017. Furthermore, we compare the model prediction for the shape of Ne II 371.308
nm spectral line which serves as a test for validity of our theo...retical model
