Abstract

High-spin states were populated in Ce-134 using the Sn-124(O-16,6n) reaction at beam energies of 120 and 125 MeV. We have observed three new, weakly populated, regularly spaced rotational bands, one with an energy spacing of similar to 60 keV and two with a spacing of similar to 100 keV. These bands are compared with similar structures in neighboring nuclei. The experimental data are also compared with total Routhian surface and cranked Woods-Saxon calculations. The band with the narrower energy spacing is assigned as a highly deformed structure with a v[(i(13/2))(3) x f(7/2)] configuration relative to he N = 72 shell gap at a deformation of beta(2) similar to 0.4. The remaining two structures are thought to result from triaxial configurations with beta(2) similar to 0.2 and y similar to -30 degrees. [S0556-2813(99)00403-3].
