For the cross section measurement of the 236U(α, 2n)238Pu reaction, 236U targets plated on the thin aluminum foil of 2 μm thickness with a target frame was required. It was demanded that the thickness of the targets range from 1 μg/cm2 to 30 μg/cm2. This work employed the method of molecular plating using
