Candidate chiral bands in 198 Tl

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