Research on Octupole Deformation of Neutron-Rich Odd-A Nuclei and High Spin States of Some Neutron-Deficient Nuclei in A=130 Region

  • Recent progressof research on high spin states in nuclear group of Tsinghua University has been reviewed.There are two parts in the content:research on octupole deformation of neutron rich odd-A 143,145Ba and 145,147La nuclei by measuring the prompt γ-rays emitted in the spontaneous fission of 252Cf and research on the high spin states of 134,137,138Ce and 122Ba in A=130 neutron-deficient region,which shows the characteristics of shape driving,the shape coexistence,the octupole correlations and the band cross.

Abstract: Recent progressof research on high spin states in nuclear group of Tsinghua University has been reviewed.There are two parts in the content:research on octupole deformation of neutron rich odd-A 143,145Ba and 145,147La nuclei by measuring the prompt γ-rays emitted in the spontaneous fission of 252Cf and research on the high spin states of 134,137,138Ce and 122Ba in A=130 neutron-deficient region,which shows the characteristics of shape driving,the shape coexistence,the octupole correlations and the band cross.
