Abstract
The Yb-174(Si-29,5n) reaction at 148 MeV with thin targets was used to populate high-angular momentum states in Po-198. Resulting gamma rays were observed with Gammasphere. A weakly populated superdeformed band of 10 gamma-ray transitions was found and has been assigned to Po-198 . This is the first observation of an SD band in the A approximate to 190 region in a nucleus with Z > 83. The J((2))) of the new band is ve ry similar to those of the yrast SD bands in Hg-194 and Pb-196. The in tensity profile suggests that this band is populated through states cl ose to where the SD band crosses the yrast line and the angular moment um at which the fission process dominates.
