Neutron deficient isotopes of 89Tc and 89mTc have been produced through the 6~ p2n)89Tc at 95 MeV and the 58Ni(35Cl, 2p2n)S9Tc reaction at 135 MeV. A rotating catcher foil system was used to collect the activities and transfer them to a measuring position for/~-V spectroscopy. The half-lives of 89Tc and 89mTc were measured to be 12.8 +__0.9 s and 12.9-t-0.8 s, respectively. The total decay energy, Qzc, for 89Tc was determined to be 7.51___0.21 MeV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
