The rarest of the naturally occurring isotopes of mercury, /sup 196/Hg (0.146% abundance), has been photochemically separated by reaction with hydrogen halides as scavengers of the excited Hg(/sup 3/P/sub 1/) 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 /sup 196/Hg in the feedstock. For the HC1 reaction the enrichment factor is 4.2, for HBr 1.4, while for HI no enrichment is found.
