Abstract

The luminescence spectra of dense inert gas mixtures with iodine vapors excited by α-particles of 238Pu and 239Pu sources were investigated from 200 to 1,000 nm. In luminescence spectra of He-I2, Ar-I2, and Kr-I2 mixtures besides atomic lines corresponding to (np-ns) transitions of inert gas atom (n = 4 and 5 for Ar and Kr, respectively) there exist 288-, 320-, 342-, and 500-nm iodine molecular bands. The 342-nm (D&3II2g - A&3II2u) band has the highest intensity in these spectra and the highest intensity in the Kr-I2mixture. The measured bandwidth of the 342-nm band is equal to 24 A (full width at half maximum). In the Xe-I2 spectrum, the 342-nm band does not exist but the 253-nm Xel* excimer band has the highest intensity in it. The measured bandwidth of the 253-nm band equals 27 Å.
