Characterisation of natural and enriched oxygen targets in lithium carbonate foils

A method for making oxygen targets in a form of lithium carbonate compound is described. Targets were prepared for nuclear physics experiments which required oxygen with a mass greater than 60 %. Both natural and isotopic enriched targets of O-18 with thicknesses of less than 1 mg/cm(2) were produced and characterised by elastic recoil detection analysis and elastic backscattering techniques. The results obtained showed that enriched foils had limited isotopic exchange when exposed to air and good stability with time compared to foils with natural oxygen.
