Some progress in research on octupole deformation around Z=56,N=88 nuclei

摘要：

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.
