Abstract: We study many-body resonances in the neuron-rich 8He and the mirror proton-rich 8C using the 4He+N + N + N + N five-body model with the isospin T = 2 system. Resonances are described with the complex energy eigenvalues as the Gamow states using the complex scaling method. In 8He, we obtain five states in which four states are resonances, and in 8C all 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 above 4He in two nuclei with the j j coupling scheme, and all the states dominantly have the p-shell configurations. From the configuration mixing, 8He and 8C give the similar results, which indicates the good symmetry in two nuclei.
