Description
Neutron-rich nuclei 147,149,151Ce have been studied via the prompt γ-ray spectroscopy of 248Cm fission fragments. A partial level scheme for 151Ce is presented for the first time, along with the high-spin structure in 147,149Ce. A rapidly changing yrast structure with neutron number is observed and it is suggested that bands in 147Ce and 151Ce are built on the νi13/2 Nilsson state. The level scheme of 149Ce displays two bands with quite similar transition energies. There is no experimental evidence for octupole deformation in any of the three nuclei. copyright 1997 The American Physical Society
