【 摘 要 】

We develop and present the universal functional formula, depending on the incident energy and the scattering angle, of the atomic angular differential elastic cross sections for hydrogen target based on the method of least squares. The results of the universal fitting function are in excellent agreement with the results calculated using the partial expansion method.
