Abstract
The nuclear structure of Tc-99 was studied using the Mo-98(He-3,pn gamma) reaction. which has populated most stales in the nucleus below 2 MeV excitation energy. The proton exit channel uas isolated from competing reaction channels by operating gamma-ray detectors in coincidence with a large-solid-angle proton detector. The experiments included gamma-ray excitation functions, gamma-ray angular distributions, and gamma-gamma coincidences. The results were interpreted using a particle-rotor model. The systematics of increasing deformations in odd-A Te nuclei are discussed.
