摘要：
About 300 transitions have been recorded in the optogalvanic spectrum of neon in the visible wavelength region 410-670 nm by axially irradiating a hollow cathode discharge with an excimer pumped dye laser. Several weak lines have been recorded including the 632.8 nm neon laser wavelength. Temporal evolution of the optogalvanic signals was studied at several wavelengths. An explanation is given for the occasional absence of correlation in intensities observed in optogalvanic effect with those measured in emission. An explanation is also given for the voltage dependent polarity changes of optogalvanic signals. Energy transfer collisions were also detected in iron-neon discharge.
