OSTI ID:917701
The measurement of the differential cross section of the exclusive electroproduction reaction gamma*p --> pi^0p in W region of the Delta^+(1232) resonance is reported. The magnetic form factor (G*_M) and ratios of electric to magnetic and scaler to magnetic multipole amplitudes R_EM = E_1+/M_1+ and R_SM = S_1+/M_1+ for the gamma*p --> Delta+(1232) transition are extracted in the framework of a unitary isobar model.
