英文摘要	An experiment of S-29 bombarding on C-12 target was performed to study the phenomena of two-proton halo and two-proton emission. The 1p and 2p removal cross sections for S-29 are 3.15 +/- 0.32b and 1.85 +/- 0.20 b, respectively. The 2p removal cross section is abnormally large. It denotes the two-proton occurs to be a halo distribution. Among the 2p-Si-27 coincident events, a strong correlation between two protons was found. The small correlation angle indicates these two protons might come from (2H)e cluster emission. Moreover, the relative momentum distribution shows the two protons locate originally at singlet 2s state and emit with strong interaction.
