Candidate chiral bands in (198)Tl

Candidate chiral bands in (198)Tl

High-spin states in 198Tl were studied using the 197Au(α, 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 πh9/2 ⊗ νi−1 13/2 band. Two-quasiparticle-plus-triaxial-rotor model...

Zusammenfassung:High-spin states in 198Tl were studied using the 197Au(α, 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 πh9/2 ⊗ νi−1 13/2 band. Two-quasiparticle-plus-triaxial-rotor model calculations suggest an aplanar orientation of the total angular momenta for these bands, thus supporting possible chirality.
