Given that it is roughly two orders of magnitude more abundant that Hg-196, the required isotopic separation, even it required a further step of separating the lighter Hg-196 from the heavier Hg-198 could be achieved with a better yield for any given effort than for Hg-196. This reaction, in addition to serving as a potential neutron source could also be used to produce Hg-197 and via electron capture produce 197Īu - stable gold. It has a non-negligible gamma ray cross section for the ( γ, n) reaction with 10 Mega- Electronvolt Gamma Rays. However, given that a costly step of isotope separation would have to precede the already costly process of transmutation, this has (as of 2022) mostly remained a theoretical curiosity rather than an actual area of research.Īt roughly 10% of natural Mercury, Hg-198 is neither particularly abundant nor particularly rare. U in natural uranium, Hg-196 is of some theoretical interest in the synthesis of precious metals via nuclear transmutation since it could - in theory - be transmutated into the only stable gold isotope 197Īu via neutron absorption and subsequent decay via electron capture. While it is the rarest stable isotope of Mercury, at a proportion lower than that of 235 ^ Believed to undergo β −β − decay to 204Pb.^ Believed to undergo β +β + decay to 196Pt with a half-life over 2.5×10 18 years.
