| Abstract: | We investigate the structures of the 0+ states in 8He from the viewpoint of dineutron correlation, i.e., spatial correlation between two neutrons coupled to a spin singlet. In this paper, we mainly discuss the \({0^+_2}\) state which is a candidate for the two-dineutron condensate state. This state has one α and two compact dineutrons expanded widely with little correlation with each other to form a gaslike structure. |
