摘要: Mesor-retardation effects in photodisintegration of the deuteron below pion threshold are studied by constructing retarded one-boson-exchange potentials using time-dependent non-covariant perturbation theory. The corresponding meson-exchange currents including vertex derived analogously gauge-invariant minimal coupling. It is found that retardation wave functions and electromagnetic as well have a significant influence on total differential cross sections.
