The high-spin states in 197Tl were studied by populating them using the 197Au(α, 4n)197 Tl reaction at 48 MeV of beam energy. γ−γ coincidence data were taken using a combination of clover, LEPS (low energy photon spectrometer) and single crystal HPGe detectors. The polarization and DCO measurements were performed for definite spin and parity assignment of the excited states. The πi13/2 intruder state has been identified for the first time in this nucleus. The total Routhian surface calculations have been performed to study the shape and deformation of 197Tl for different configurations.
