Abstract
Many studies employing various methods have been carried out into the number
densities of excited atoms in electrical discharges with inert gases [1,2,3], but the
ranges of the discharge current and gas pressure is very limited in them all. In this
work, the population densities of 3S, 3s' of neon have been investigated using the
atomic absorption method. Since the discharge current and gas pressure have marked
effects on the variation of these densities, the pressure range of 0.1-15 m. bar and
currents up to 30 mA have been used
