摘　　要：The Reflection Asymmetric Shell Model has been formulated to describe the high spin states of octupole deformed nuclei.The long-range separable forces of quadrupole,octupole and hexadecapole as well as monopole and quadrupole pairing are included in the Hamiltonian.The bases,on which the Hamiltonian is diagonalized,are the eigenstates of angular momentum and parity obtained by projecting the octupole deformed multi-quasiparticle states onto good angular momentum and good parity.The general features of rotational octupole bands in even-even nuclei can be reproduced by the model and the calculated result is in good agreement with experiment.
