The 4He(p,2p)3H reaction was studied in a coplanar symmetric geometry at 350 MeV and 500 MeV using the proton beam of the TRIUMF cyclotron. At both incident energies we measured the energy sharing spectrum at the quasifree equal angles as well as the symmetric angular distribution. Out data resolve the discrepancy between the zero‐recoil cross sections measured at 460 MeV and at 590 MeV in favor of the 590 MeV SREL result. The excess of high‐momentum components in the 590 MeV angular distribution data, as compared to impulse approximation calculations, is confirmed and extrapolated to higher momenta.
