Quantum theory of distorted-wave Born approximation (DWBA) can be applied to the electron impact ionization, i.e.(e, 2e) process. In particular, the data of cross section for the electron-atom ionization collision are theoretically predicated by DWBA, and it covers the electron energy level in materials processing. Furthermore, electron energies and the angle between two scattered electrons after the collision can be obtained. They are quantum mechanically measurable, and the quantitative comparison of them between the theory and the experiment can be made in detail. Previous works often omitted the exchange term of the basic equation after the partial wave decomposition of Schrodinger equations, and it results the serious disadvantage from the viewpoint of engineering. In the present paper, novel method for numerically solving the basic equation in electron-hydrogen scattering is presented based on the iterative methods. The validity of the present study is discussed based on previous similar works.
