Dimensions of the layers of positive space charge in a high-frequency discharge

Based on investigating the spatial distribution of the radiation intensity in molecular bands of nitrogen ions the authors determined the widths of the layers of positive space charge in mixtures of molecular gases in transverse HF excitation. It is shown that contrary to predictions of the elementary theory these widths depend relatively weakly on the excitation frequency and the gas pressure.
