The Chew meson theory has been applied in an attempt to describe the photodisintegration of the deuteron in the region of 100 to 400 Mev, and in particular to explain the appearance of a sort of resonance at about 250 Mev. The process is viewed as a meson photoproduction, followed by meson scattering in deuterium (treated in the impulse approximation) and absorption. The qualitative features of total cross section are roughly reproduced, but the angular distribution does not seem to be fully understood on this model.
