Fluorescence and Electron Energy Loss Cross Sections in Mercuric Bromide.
Abstract
Computer modelling of HgBr discharge lasers requires as input the various cross sections for electron impact on HgBr2. This report describes measurements of the wavelength resolved emission cross section measured between 240 and 530 nm. This range encompasses three bands: The (D-X), (C-X) and B-X which have been documented and discussed previous. In addition we find a fourth band which appears on the long wavelength side of the (C-X) band, and overlaps the short wavelength tail of the (B-X) band. Measurements of the wavelengths at which local maxima appear in the fluorescence agree acceptably with Wielands' data on this band, which we designate as the (B'-X) band. A systematic approach to partitioning the spectrum between the various bands has been adopted in order to derive total band emission cross sections for all four bands. A more extensive series of measurements on the benchmark He line emission cross sections has led to a revised method of calibration the HgBr data.
