Abstract: | Expressions for the zero frequency dynamical structure factor, S(k, ω = 0), are derived from the theory of collective motion of liquids proposed by the authors and that by Hubbard and Beeby. Calculations on liquid argon show that in comparison with the latter, the former theory gives much higher values of S(k, 0) which are in good agreement with the recent experimental results. |
