Abstract ： 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.
