Abstract
Two-dimensional γ-ray energy correlations have been measured at high spins in1800s with the TESSA2 spectrometer. The Eγ − Eγcorrelation matrix displays ridges characteristic of rotational bands with different energy separations of 96± and 72± keV for the energy regions of 660 to 840 keV and 975 to 1170 keV, respectively. The separation of these ridges remains constant in both energy regions. The dynamical moments of inertia are θ(2) =83±3 and 111±5 ħ2/MeV, respectively. The latter value suggests superdeformation in1800s with an axis ratio c/a=1.76 (β2 ≅0.64) at high spins.
