Abstract：
High-spin structures in ¹⁴⁶Ce nucleus have been re-investigated by measuring the prompt γ rays from spontaneous fission of ²⁵²Cf. The previously reported level scheme of ¹⁴⁶Ce has been updated. The octupole deformed collective bands have been extended up to higher spin states. A possible quasi-γ band structure was examined and reconstructed according to our data analysis. In addition, the reflection asymmetric shell model was applied to describe the octupole deformed bands in ¹⁴⁶Ce, and the calculated results are in good agreement with the experimental data at lower spins.
