| Abstract: | High-spin states of 103 43Tc have been identified for the first time, this nucleus being produced as fission fragment following the fusion reaction 37Cl + 176Yb 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 97-105Tc 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. Received: 19 January 2001 / Accepted: 23 February 2001 |
