我们使用同位旋系统的五体模型研究了富含神经元和富含镜像质子的多体共振。使用复标度方法将共振用复能量特征值描述为伽莫夫态。在，我们得到五个状态，其中四个状态是共振，并且所有五个状态都是共振。我们讨论了能谱中库仑相互作用动态引起的同位旋对称性破缺和两个镜核共振的衰变宽度。我们预测未来实验的共振能量和衰减宽度。我们还用耦合方案研究了两个原子核中上述价核子的构型，所有态都主要具有壳层构型。从构型混合来看，给出了相似的结果，这表明两个原子核具有良好的对称性。
We study many-body resonances in the neuron-richand the mirror proton-richusing thefive-body model with the isospinsystem. Resonances are described with the complex energy eigenvalues as the Gamow states using the complex scaling method. In, we obtain five states in which four states are resonances, and inall five states are resonances. We discuss the isospin-symmetry breaking dynamically induced by the Coulomb interaction in the energy spectra and decay widths of the resonances in two mirror nuclei. We predict the resonance energies and decay widths for the future experiments. We also investigate the configurations of valence nucleons abovein two nuclei with thecoupling scheme, and all the states dominantly have the-shell configurations. From the configuration mixing,andgive the similar results, which indicates the good symmetry in two nuclei.
