英文摘要	The A = 4 nuclei, i.e., H-4, He-4, and Li-4, establish an interesting isospin T = 1 isobaric system. H-4 and Li-4 are unbound broad resonances, whereas He-4 is deeply bound in its ground state but unbound in all its excited states. The present situation is that experiments so far have not given consistent data on the resonances. Few-body calculations have well studied the scatterings of the 4N systems. In the present work, we provide many-body calculations of the broad resonance structures, in an ab initio framework with modern realistic interactions. It occurs that, indeed, H-4, Li-4, and excited He-4 are broad resonances, which is in accordance with experimental observations. The calculations also show that the first 1(-) excited state almost degenerates with the 2(-) ground state in the pair of mirror isobars of H-4 and Li-4, which may suggest that the experimental data on energy and width are the mixture of the ground state and the first excited state. The T = 1 isospin triplet formed with an excited state of He-4 and ground states of H-4 and Li-4 is studied, focusing on the effect of isospin symmetry breaking.
