Abstract: High-spin states in <superscript>198</superscript>Tl were studied using the <superscript>197</superscript>Au( $ \alpha$, 3 n) reaction. The level scheme was considerably extended including two new bands and several non-yrast levels. One of the new bands is possibly a chiral partner to the yrast $ \pi$ h<subscript>9/2</subscript>⊗ $ \nu$ i<subscript>13/2</subscript> <superscript>-1</superscript>band. Two-quasiparticle-plus-triaxial-rotor model calculations suggest an aplanar orientation of the total angular momenta for these bands, thus supporting possible chirality. [ABSTRACT FROM AUTHOR]
