Abstract：
The reflection asymmetric shell model (RASM) has been applied to describe the
alternating-parity rotational bands in neutron-rich ^{142,144,146,148}Ba octupole nuclei. The calculated rotational bands are in good agreement with the available experimental data. The parity splitting and the parity inversion are also reproduced by the present calculation.
