N2 - This is the first kinematically complete measurement of the 4He(γ, npp)n reaction in the energy range of 135-455 MeV. The ordered-momentum spectra and the double-differential cross sections are compared with the calculations which assume that photons are absorbed either on two- (np or pp), three- (npp), or four-nucleon systems. The ordered-momentum spectra below 400 MeV are reproduced well by pp and/or npp absorption but not by np absorption only.
