摘要：

The direct differential cross section and the total cross section for scattering of 0.5-. 1.5-, and 5.0-keV H+, H, and He projectiles by He and Ne targets over the laboratory scattering angle range 0.01 degrees-10.0 degrees are studied using the electron nuclear dynamics theory, which treats the simultaneous dynamics of all electrons and nuclei. Emphasis is put on the quantum effects of the forward peak scattering. Comparison of the present results with available experimental data shows very good agreement.
