Photonuclear production of 18F from F, Ne and (metallic) Na
Cross sections per equivalent quantum (σq) have been measured for photonuclear reactions yielding 18F from LiF, SF6, CF4, Ne and metallic Na targets, in the energy range 77–125 MeV. The σq values for LiF and Na are conformable with known data, whilst the σq values for SF6 and CF4 are found to be 10% lower than for LiF. The utility of metallic Na as a target for 18F production has been demostrated by a nucleophilic substitution reaction with (C2H5)4N18F, formed after dissolution of irradiated Na in absolute C2H5OH.
