| Abstract: | We study the resonance spectroscopy of the proton-rich nucleus 7B in the 4He + p + p + p cluster model. Many-body resonances are treated under the correct boundary condition as Gamow states using the complex scaling method. We predict five resonances of 7B and evaluate the spectroscopic factors of the 6Be-p components. The importance of the 6Be(2+)-p component is shown in several states of 7B; this is a common feature of 7He, a mirror nucleus of 7B. For only the ground state of 7B, the mixing of the 6Be(2+) state is larger than that of 6He(2+) in 7He, which indicates a breaking of mirror symmetry. This is caused by the small energy difference between 7B and the excited 6Be(2+) state, the origin of which is Coulomb repulsion. |
