Satisfactory behavior of the back scattering factor was obtained in the latter case. The obtained back scattering factor is similar to the case of one component hard spheres. The mutual diffusion coefficient was, within ten percent, in agreement with the linear relation of particle number ratio between respective self-diffusion coefficients. Some discussions were given for the role of mass difference on the mechanism of diffusion., 資料番号: AA0029039010, レポート番号: NASDA-TMR-000013E}, title = {Molecular dynamics simulation of hard sphere mixtures}, year = {2001} }
