Abstract

High spin states in neutron-rich Ce147 have been reinvestigated by measuring the triple- and fourfold γγ coincidence data observed in the spontaneous fission of Cf252. The positive-parity band is expanded to spin (45/2) and the negative-parity side band is expanded to spin (39/2) with a new third band connected to it. An octupole band structure with s=+i was proposed. The systematic characteristics of the octupole correlations have been discussed. Reflection asymmetric shell model calculations for the octupole band structure of Ce147 are in good agreement with the experimental data.
