Abstract
Production of (38)Cl and (34m)Cl via the (d, α) reaction on natural argon and (36)Ar reveal medical cyclotrons' ability to supply these isotopes in small quantities. (38)Cl provides an inexpensive developmental tool, while (34m)Cl is a positron emitter of interest in PET imaging. Production yields, cyclotron target development, cryo-recovery of enriched gases, and nucleophilic chemistry of a model compound are described.
