Thin target covered with Pb film is widely used in the study of nucleus high spin states. The preparing method of Tb target was described in detail. The thin Tb target was obtained by rolling method and the Pb film was prepared by rolling or vacuum evaporation. The combination of Tb and Pb films was completed by means of rolling or vacuum evaporation. The target of Tb covered with Pb film obtained from this method is smooth
bright
tough and pinhole-free. It has been successfully used in the experiments.
