摘　　要：The reflection asymmetric shell model （RASM） has been developed to describe the octupole deformed odd nuclei. With the RASM the calculated rotational bands have good angular momentum and good parity and then can be directly compared with the experimental rotational bands. In this report, we have applied this model to describe the octupole deformed bands of the neutron-rich even-even nucleus ^142Ba. The quarupole-, octupole- and hexadecapole- deformation parameters used in this work are 0.127,
