摘要: We explore the possibility that a stable nucleus has halolike structure in high isospin excited states. As an example of 3.563 MeV ${0}^{+}$ state $^{6}\mathrm{Li}$ is studied fully microscopic \ensuremath{\alpha}+p+n three-cluster model, because it isobaric analog $^{6}\mathrm{He}$ with two-neutron halo structure. An extensive calculation mixing shown spatially extended formed by neutron and proton outside \ensuremath{\alpha} particle. Electron scattering form factors related are reproduced fairly well.
