The differential and total cross sections for the photodisintegration of the deuteron are calculated for the incident photon energies in the range from 80 Mev to 300 Mev. In the calculation, a full expression of the electric interaction between the deuteron and radiation is used without expansion in terms of kr of each multipole or multipole transition. For the initial state, we adopt the pion-theoretical deuteron wave function which has almost 7% of D-state mixture. The plane wave is used for the final state. The conclusions are 1) kr expansion is not justified in the energy range E_γ≳ 80 Mev and gives an underestimate for the cross sections, 2) the multipoles higher than E2 do not affect for E_γ&Isim; 80 Mev, 3) the large D-state mixture is important, 4) the retardation effects are important at such high energy as the meson effects have to be considered. It is shown that the excitation function agrees with the observed data in the energy range, if we add the meson effects to our result.
