High-spin states in {sup 122}Cs have been studied via {sup 107}Ag({sup 19}F, p3n){sup 122}Cs fusion evaporation reaction at beam energy of 93 MeV. Fifteen new transitions belonging to {sup 122}Cs have been observed and placed in the level scheme. The level structure of {sup 122}Cs has been extended up to E{sub x}{approx_equal}7 MeV and J{approx_equal}28({Dirac_h}/2{pi}). We have performed the linear polarization measurements using the Clover detectors to assign the unknown spins and parities of a few bands. We have also observed a few linking transitions between negative and positive parity bands indicating the octupole collectivity in this nucleus. The structure of the various bands are discussed in the frame work of the cranked Hartree-Fock-Bogoliubov model and the microscopic projected Hartree-Fock model calculations.
