High spin states in 194Tl, excited through the 181Ta (18O, 5n)194Tl heavy-ion fusion evaporation reaction were studied at iThemba LABS using the AFRODITE array, which consisted of 8 clovers and 6 LEPS detectors. The yrast band built on the 8- isomeric state has a \pi h9/2 \otimes \nu i13/2-1 configuration suitable for a chiral system. One of the new bands built on a new 10- level has the same parity and similar excitation energy to those of the yrast band. This new band is linked to the yrast band by several transitions and may be a chiral partner to the yrast band.
