Abstract.

High-spin states in 198Tl were studied using the 197Au(\( \alpha\), 3n) 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 9/2⊗ \( \nu\) i 13/2 -1band. Two-quasiparticle-plus-triaxial-rotor model calculations suggest an aplanar orientation of the total angular momenta for these bands, thus supporting possible chirality.
