%X To evaluate the PET-imaging properties of the promising positron emitter 45Ti, its β+- and γ-ray intensities were measured. Use of the cation-exchange resin DOWEX 50W×8 (H+-form) enabled the isolation of radiochemically pure, no-carrier-added 45Ti from “bulk” scandium after proton bombardment. Thin, no-carrier-added 45Ti samples were prepared. The combination of γ-ray and X-ray spectrometry with γγ-coincidence counting allowed for the first time the experimental determination of the positron intensity as (85.67 ± 2.23)% and the absolute intensity of the 720.22 keV γ-ray as (0.1171 ± 0.0057)%.
