Abstract The recoil reactions of technetium produced by100Ru/γ, p/99mTc reaction were studied in γ-irradiated mer- and fac-Ru/ba/3 targets. Yields of mer- and fac-Tc/ba/3 were determined by column chromatographic separation developed in our previous work. In the initial recoil reaction yields mer-form of Tc/ba/3 was much more abundant than fac-form in the mer-Ru/ba/3, but the reverse held good in the fac-Ru/ba/3 showing selectivity in recoil replacement reactions in geometrical isomers. In the annealing reactions, however, such selectivity disappeared and the fac/mer ratio for the annealed portions could be explained by the following mixed mechanisms of ligand incorporation. $$\begin{gathered} Tc/ba/_2^ + + ba^ - \to Tc/ba/_3 \hfill \\ Tc/ba/^{2 + } orTc^{3 + } + xba \to Tc/ba/_3 \hfill \\ /x = 2or3/. \hfill \\ \end{gathered} $$
