A simple model within the framework of partial wave expansions in the adiabatic approximation is developed to calculate the elastic and inelastic scattering of high energy nucleons or composite systems of nucleons from nuclei. It is shown that the present model, apart from a multiplicative form factor depending on scattering angles and the nuclear surface thickness, is approximately equivalent to that of the diffraction of waves by a black sphere of radius equal to that of the target nucleus in the Fraunhofer approximation. There appear two parameters in the formulation. One is the effective equilibrium radius of the target nucleus and the other is the effective thickness of the nuclear surface. The model is applied to analyze the recent experimental data from Saclay on the elastic and inelastic scattering of 1.37 GeV ..cap alpha.. particles from /sup 40,42,44,48/Ca. It is found that the calculated differential cross sections of elastic and inelastic scattering and those measured experimentally are in very good agreement.
