摘　　要：The conventional proton resonance scattering has been a powerful spectroscopic tool to explore the properties of compound nucleus levels close to the threshold, which is usually of astrophysicalThe conventional proton resonance scattering has been a powerful spectroscopic tool to explore the properties of compound nucleus levels close to the threshold, which is usually of astrophysical and structural significance. It is a kind of precise yet very time-consuming experiment, since one needs to change the proton beam energy in small steps in order to obtain an excitation function of the energy range of interest. To use radioactive ion beams with limited intensity and short lifetime, more efficient experimental method with the emphasis of inverse kinematics must be employed. For this purpose, the thick target method has been proposed and rapidly applied. It uses an either solid or gas target containing hydrogen atoms with thickness enough to stop the beam ions or degrade its energy to the region of interest. By measuring the lighter recoil particles at laboratory forward angles, one can rebuild the reaction kinematics taking account of the energy losses of particles in the target. The method allows one to study several resonances simultaneously by using a single bombarding energy of exotic beam.
