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.
