The projected shell model is employed to interpret multi-quasiparticle energy bands in odd-mass neutron-deficient 117–121Cs isotopes. The experimentally known energy bands and their configurations are reproduced well by employing this approach. The analysis of theoretical results predicts the low-lying spin states to arise from the single quasiparticle band albeit the high-spin states are seen to arise from the superposition of three quasiparticle bands. In addition, the experimentally known signature partner bands and band head energies are also predicted in these isotopes which can serve as a clue for planning new experiments.
