Abstract
High-spin states of Tc-103(43) have been identified for the first time, thi s nucleus being produced as fission fragment following the fusion reaction Cl-37 + Yb-176 at 170 MeV bombarding energy. The high-spin level scheme has been built from the prompt gamma rays detected using the Euroball III arra y. It exhibits similarities with those of tile neighbouring: isotopes and i sotones. All the band head configurations observed in the Tc97-105 isotopes are identified front the behaviour of the rotational bands built on them. The single-proton states located around the Fermi level are discussed as a function of deformation of these nuclei.
