| Popis: |
High-spin states of the odd-odd nucleus Lu-168 were populated in the Sb-123(Ca-48, 3n) Lu-168 reaction at a beam energy of 203 MeV and decay gamma rays measured using the Gammasphere spectrometer array. The level scheme has been extended from spin 27 to 50 (h) over bar, and three new rotational bands have been added. A number of interband linking transitions were revealed, so that all but two bands could be connected with each other. High-spin band crossings, above the first vi(13/2) alignment, are delineated in most bands. Significant signature inversions are identified for the first time in the bands involving both favored and unfavored signatures of the pi h(9/2) orbital, which are likely caused by a residual proton-neutron interaction. A signature inversion with small amplitude is also observed in the pi d(5/2) circle times vi(13/2) band. Configurations are suggested for all bands based on their experimental properties, with the help of Cranked Shell Model calculations. No evidence is found for triaxial strongly deformed structures that were predicted by the calculations. |
