Theoretical description of octupole deformed band in neutron-rich even-even Ba isotopes

摘要

The reflection asymmetric shell model (RASM) has been applied to describe the alternating parity rotational bands in neutron-rich 142,144,146,148Ba 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.
