Photochemical isotope separation of Hg-196 by reaction with hydrogen halides
Description
The rarest of the naturally occurring isotopes of mercury, 196Hg (0.146% abundance), has been photochemically separated by reaction with hydrogen halides as scavengers of the excited Hg(3P1) atoms. A separation of 2 to 3 mg/h of enriched calomel product is achieved by using a monoisotopic lamp as an excitation source. The product contains 22 +- 8% of the 196Hg in the feedstock. For the HC1 reaction the enrichment factor is 4.2, for HBr 1.4, while for HI no enrichment is found
