Abstract:

High-spin states have been studied in 101Tc produced as a fission fragment in the reaction 176Yb +28Si at 145 MeV. Gamma rays were detected with the EUROGAM2 array. The level scheme of 101Tc has been extended up to 4.2 MeV excitation energy and several band structures are observed. Configurations are assigned to two new bands on the basis of their behaviour and of cranked Hartree-Fock-Bogolyubov calculations.
