Abstract：
Using particle-rotor model,the γ transition energies,signature splitting and M1 transitions for the yrast superdeformed band in odd-A Tl isotopes are investigated and compared with the experimental data.The small difference in the moments of inertia and signature splitting when going from the heavier Tl isotope to lighter ones is thought to reflect the gradual decrease of the quadrupole deformation.The (g_Kg_R)K/Q₀ values enable us to confirm that the 81st proton occupies the [642 5/2]orbital.
