The results of experimental study of Ne emission in the wavelength range of 200 - 600 nm under excitation by electric discharge and short-duration e-beam are presented. It was found that temporary behavior of the emission intensity distinguished in different spectral regions. The nature of the radiation in the ranges of 120 - 300 nm and of 300 - 500 nm was suggested due to transitions of molecular ions and those from Rydberg states Ne$-2$/$+R$/, respectively.
