Emission characteristics of an ultraviolet radiation source excited with the help of a pulse-periodic capacitive discharge in the mixtures of helium, neon, and krypton with iodine vapors and emitting in the spectral range of 180-450 nm is investigated. It is shown that the dominant part of the radiation power of the lamp is concentrated in the 183.0-nm and 206.2-nm spectral lines of iodine atom and the $D'-A'$ band of iodine molecule with a maximum close to 342 nm. The radiation intensity of the lamp is optimized with respect to the partial pressure of the inert gases. The parameters of the discharge plasma in the mixtures of iodine vapors with Не and Хе atoms are calculated, which is of interest for the modeling of plasma kinetics and output characteristics of UV radiation sources operating on the iodine and xenon iodide molecules and iodine atom.
