The result of proton polarization measurements (period 1993-2000) in the photodisintegration of the nuclei D, ³He, ⁴He at the photon energies E=350-750 MeV are presented. The proton polarization was measured on the 2 GeV linac NSC KIPT with a carbon polarimeter and a magnetic spectrometer. The proton polarization for the nuclei ³He and ⁴He is first measured and analyzed within the framework of "quasi-deuteron" model.
