Abstract
Net emission coefficients were calculated for a two-dimensional HID light source in accordance with the composition, the local temperature, and the radiation relative to the rest of the discharge which can be absorbed in the same volume of an element. All important line-broadening mechanisms were included, and the effects of emission and absorption on the net emission coefficient were accounted for on a line-by-line basis. Particular attention has been paid to the effect of pressure on the net emission of the 253.7 nm resonance line and the visible lines. Published under an exclusive license by AIP Publishing.
