Abstract：
Level structures of ⁸⁵Br have been investigated using the shell-model code nushellx within a large model space containing the neutron-core excitations across the N=50 closed shell. The calculated results have been compared with the available experimental data. Reasonable agreement between the experimental and calculated values is obtained, which indicates that the neutron-core excitations are essential to reproduce the level structures of ⁸⁵Br. The systematic features of neutron-core excitations in the N=50 isotones are investigated.
- level structure,
- shell-model,
- neutron-core excitations
