โœฆ Synopsis

Separation of carbon i2113 isotopes has been achieved by selective predissociation of formaldehyde using a frequer.cydouble dye laser. The ~n~chme~t factor for pure formaldehyde samples is fess than expected from spectroscopic data but is greatly improved by the addition of NO. Starting from a 1:lO mixture of in 12C0 has bean obtained.

The application of lasers to the field of isotope separation has received a great deal of attention in recent years {l,2]. In this paper we report the separa. tion of carbon isotopes using a fr~quenc~doubled dye laser to selectively predissociate form~dehyde. Ar. eightl-fold enrichment of' l2 CO from a 10% mix-
