文摘The electro production cross sections of ed→ed^(*) have been calculated based on the meson exchange current model.The cross section around 30°of 1 GeV electron in the laboratory frame is about 10 nb,which is about two orders smaller than that of the quasi-elastic and Δ resonance production.A special kinematics and detector system must be studied to pin down the weak signal of d^(*) resonance from the strong background.
