Abstract
The high-spin structure of the nucleus has been studied by using the (, reaction to search for chiral doublet bands based on the three-quasiparticle configuration. The level scheme of has been extended. New bands were found and the placement of the yrast band was corrected. No side band to the yrast band could be found in the present experiment. This observation indicates that the γ-soft shape in the changed to a more γ-rigid axially symmetric shape in the yrast configuration. However, a new pair of bands was observed to show the expected properties of a chiral doublet structure.
