Ultraviolet Absorption Cross-Section of Mercuric Bromide.

Abstract

This report is on the measurements of the ultraviolet absorption cross section of mercuric bromide (HgBr2) from 175.0 nm to 325.0 nm and discusses the need for such measurements. The ultraviolet radiation wavelengths from a hydrogen discharge lamp were selected by a vacuum monochromator (0.25 nm resolution) and passed through an absorption cell, made of fused quartz, containing the HgBr2. The experiments were conducted over the temperature range 110 C to 150 C corresponding to vapor pressures of 0.2 torr to 2.15 torr of the HgBr2. The results of this study are compared with the results of previous studies and clears up several discrepancies concerning the value of the absorption cross section. It further measures the value of the cross section of an absorption band at 184 nm that was not previously available. (Author)
