Abstract
Neutron-rich nuclei Ce have been studied via the prompt -ray spectroscopy of Cm fission fragments. A partial level scheme for Ce is presented for the first time, along with the high-spin structure in Ce. A rapidly changing yrast structure with neutron number is observed and it is suggested that bands in Ce and Ce are built on the Nilsson state. The level scheme of Ce displays two bands with quite similar transition energies. There is no experimental evidence for octupole deformation in any of the three nuclei.
