The calculation is carried out by the simple purely theoretical method, i.e. by the viscoelastic theory, which is based on the effective pair potential obtained by the pseudopotential perturbation theory and the static structure factor calculated by the integral-equation theory in the modified hypernetted-chain (MHNC) approximation. It is shown that the calculated dynamical structure factors are in qualitative agreement with the experimental results and that the calculated dispersion relation agrees well with the experimental one. 資料番号: AA0045399001 レポート番号: NASDA-TMR-020025E 宇宙開発事業団 National Space Development Agency of Japan (NASDA) 2002-12-27 eng technical report https://jaxa.repo.nii.ac.jp/records/42821 1345-7888 AN00364784 宇宙開発事業団技術報告: Modeling and Precise Experiments of Diffusion Phenomena in Melts Under Microgravity: Annual Reports 2001 NASDA Technical Memorandum: Modeling and Precise Experiments of Diffusion Phenomena in Melts Under Microgravity: Annual Reports 2001 53 60 https://jaxa.repo.nii.ac.jp/record/42821/files/45399001.pdf application/pdf 435.9 kB 2020-02-10
