Abstract：
By using the real part of the optical potential obtained in the folding model calculation and the imaginary part of the optical potential of Koning and Delaroche, the data of the proton elastic scattering off ^30—40S are calculated and analyzed. By introducing the one-body density matrix of nuclear shell model with Woods-Saxon potential, the local approximation which is usually used in the folding model can be eliminated. The effects of the local approximation on the folding potential and the cross sections of elastic scattering are analyzed. The calculated results are compared with those of the folding model and JLM model.
