Two-proton decay is a quantum tunneling process. The tunneling probability depends on the available energy and the height of the Coulomb barrier, which in turn depends on the nuclear charge Z (number of protons). Two-proton emission is a typical three-body breakup process, including the daughter nucleus and two protons, in which pairing correlations play an important role. Therefore, a detailed study of two-proton emission is of great significance for exploring the open quantum system, pairing correlations and exotic nuclear structure.
