英文摘要	Two-proton emissions from the excited states of Ne-17,Ne-18 and S-28,S-29 were investigated by the radioactive beams bombarding on the Au-197 target via the Coulomb excitation. The complete-kinematics measurements were actualized by the stacks of silicon-strip detectors and CsI+PIN array detectors. The invariant mass of final systems as well as the relative momentum, opening angle, and relative energy of the two emitted protons were reconstructed under the framework of relativistic kinematics. The mechanisms of two-proton emission were analyzed in a simple schematic model. With the help of Monte-Carlo simulations, the two protons emitted from the 6.15 MeV excited state of Ne-18 and the excited states around 10 MeV of S-29, respectively, exhibit prominent features of He-2 decay. While for the other states, no obvious diproton emissions were observed.
