Abstract：
Recent progress in research on octupole deformation around Z=56, N=88 neutron-rich nuclei by our cooperative groups of Tsinghua University, Vanderbilt University and Lawrence Berkeley National Laboratory has been introduced. The experiment was carried out by measuring the prompt γ-rays in spontaneous fission of ²⁵²Cf with the Gammasphere detector array. The new results of
high spin states in ¹⁴³La and ¹⁴⁸Ce have been obtained and the octupole deformation bands are identified in both nuclei. The important structural characteristics have been discussed.
