Probing alternating-parity bands in even-even nuclei within an axial quadrupole-octupole-hexadecapole collective model

M. Chabab, A. El Batoul, L. El Ouaourti

An analytic quadrupole octupole hexadecapole (QOH) axially symmetric model is used to provide a coherent framework for describing both octupole vibrations and octupole deformations…
