Photoemission of protons from He4 is measured at p=30°, 60°, 90°, and 105°in the photon energy range between 187 and 427 MeV. From the analysis of the momentum spectrum of protons, the differential cross sections for the photodisintegration of quasifree two-nucleon systems in the He4 nucleus are deduced as a function of the proton angle and the incident photon energy. The obtained cross sections for He4 are larger than those for the deuteron photodisintegration by a factor of about 4.5 in the energy region of the present experiment.
