Field ion microscope images of gold hava been obtained employing helium, a 25% neon- helium gas mixture, neon, and argon as imaging gases both with and without prior hydrogen promoted field evaporation of the specimen. The helium images were unstable, while the 25% neon-helium, neon and argon images were quasi-stable at best image field. The 25% neon-helium images had an artifact vacancy concentration of ∼ 10-3 in the {210} planes, while the pure neon images exhibited artifact vacancies in every well resolved high index plane. The argon images showed a strong degree of disorder, even though individual atoms were well resolved. A brief discussion of possible mechanisms for artifact vacancy formation in gold is given.
