抄録	In neutron-rich nuclei neighboring Si-42, the quenching of the N = 28 shell gap occurs and is expected to induce shape coexistence in their excitation spectra. We have applied the theoretical framework of antisymmetrized molecular dynamics with the Gogny D1S density functional to describe the shape coexistence in the N = 28 isotones Mg-40, Si-42, and S-44. We show that different nuclear shapes coexist in these nuclei: Rigid shapes with different deformations coexist in Mg-40 and Si-42, while S-44 exhibits large-amplitude collective motion and does not have any particular shape. These characteristics are reflected well in the monopole transition strengths that can be utilized as a probe for the shape coexistence.
