In the present paper a new model of the high energy scattering of nucleon from complex nuclei is presented. Under the assumption that the short-range correlation between nucleons and the Pauli principle in the target nucleus in its ground state plays an essential role in the high energy elastic scattering, one can predict the angular distribution of the high energy elastic scattering from heavy nuclei to be characterized by the following important results: (i) the positions of maxima and minima coincide respectively with those given by the impulse approximation, (ii) the absolute value of the angular distribution is multiplied by a constant factor |λ|^2 to that given by the impulse approximation, (iii) this factor is a constant independent of mass number and nearly independent of the incident energy in heavy nuclei, and finally, (iv) the magnitude of √<|λ|^2> is of order 0.4~0.5. This factor results from the Pauli principle in the target nucleus. In fact, analysis of the experimental data shows that the above expectation is valid. Here we take the scattering of 95 Mev proton. The factor √<|λ|^2> is equal to 0.55 for Cu and heavier nuclei to Th, in the case of meson theoretical phase shift. √<|λ|^2>=1 for C, 0.75 for Al.)
