Abstract
Neutron deficient isotopes of89Tc and89mTc have been produced through the60Ni(32S,p 2n)89Tc at 95 MeV and the58Ni(35Cl, 2p 2n)89Tc reaction at 135 MeV. A rotating catcher foil system was used to collect the activities and transfer them to a measuring position forβ-γ spectroscopy. The half-lives of89Tc and89mTc were measured to be 12.8±0.9 s and 12.9±0.8 s, respectively. The total decay energy, QEC, for89Tc was determined to be 7.51±0.21 MeV.
