Recent experimental data on odd-mass iodine isotopes (A=119-125) have revealed several interesting structural features. These include the observation of coexistence of prolate and oblate bands with similar proton configurations, three quasi-particle bands, signature inversion in yrast positive-parity bands, shape coexistence. Presently particle rotor model calculations have been performed for the π h_11/2, π g_9/2 and π g_7/2 bands in ^121,123,125I using an axially symmetric deformed Nilsson potential. The calculations reproduced the experimental results well and predict a moderate quadrupole deformation ∼0.2 for these bands.
