摘要

High-spin states of _(43)~(103)Tc have been identified for the first time, this nucleus being produced as fission fragment following the fusion reaction ~(37)Cl + ~(176)Yb at 170 MeV bombarding energy. The high-spin level scheme has been built from the prompt gamma rays detected using the Euroball III array. It exhibits similarities with those of the neighbouring isotopes and isotones. All the band head configurations observed in the ~(97-105)Tc isotopes are identified from 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.
