Reinvestigation of octupole bands in neutron-rich 141Xe

High-spin level structures in neutron-rich 141Xe nucleus have been reinvestigated by measuring the triple fold and four-fold γ coincidence data obtained in the spontaneous fission of 252Cf. Several new levels and transitions are identified. The previously proposed octupole bands have been significatively updated and expanded. The systematic characteristics of the octupole deformation and octupole correlations are discussed. Reflection asymmetric shell model calculations for the octupole bands of 141Xe are in good agreement with the experimental data.
