Abstract：
The high spin states and octupole deformation collective bands of neutron-rich nuclei ^144,146Ce have been established through measuring the prompt γ-rays from spontaneous fission of ^{<252/sup>Cf. The highest spin state is up to 15^－. The characteristics of octupole deformation for the two nuclei are discussed.}
