Abstract
Recoil implantation of Tc and Ru in metal acetylacetonates were performed using ruthenium metal as a source and MIII/acac/3 and MII/acac/2 complexes as catchers. The recoil atoms were obtained by100Ru/γ, p/99mTc and98Ru/γ, n/97Ru reactions. The yields of Tc/acac/3 and Ru/acac/3 were clearly dependent on the force constant of the bond between the central metal atom and oxygen in acetylacetone K/M-O/. A plot of the yield vs. 1/K(M-O) showed a linear relationship. However, the yield of Tc/acac/2 implanted in M/acac/2 did not show such a dependence on the force constant. The difference of the mechanism of complex formation between Tc/acac/3 and Tc/acac/2 was discussed on the basis of a reaction cage surrounding the recoil atom and of reaction time necessary for competition between the recoil atom and the central metal of the catcher complex.
