Remarkable progress in the study of two-proton emission has been made in recent years.One of the next destinations is the realization of high-precision direct measurements of decay-energy and emission-angle correlations inβ-delayed two-proton(β2p)emission.We have studiedβ2p correlated emission of the ground state of 26P at the proton drip line with the direct measurement at the National Remarkable progress in the study of two-proton emission has been made in recent years. One of the next destinations is the realization of high-precision direct measurements of decay-energy and emission-angle correlations in beta-delayed two-proton (beta 2p) emission .We have studied β2plated emission of the ground state of 26P at the proton drip line with the direct measurement at the National
