Abstract
The structures of the first \(1/2^+\) unbound states of \(A=9\) mirror nuclei are studied in the complex scaled \(\alpha +\alpha +N\) three-body model. The results indicate that the \(1/2^+\) state of \(^9\)Be is a virtual state of the s-wave neutron around the \(^8\)Be (\(\alpha -\alpha \)) cluster. But the corresponding analog \(^9\)B\((1/2^+)\) state is predicted as a resonant state due to the Coulomb barrier.
