Abstract :
Detailed dynamical structure factors, for liquid Hg in vast temperature and pressure range, has been computed using modified microscopic theory. Three samples of liquid Hg at T=1273K, 1673K and 1803K, corresponding to densities 10.98 g/cc, 9.25g/cc and 6.8g/cc, have been considered for theoretical investigation. Computed results are compared with another available reported theoretical data as obtained from molecular dynamics simulation. Results from two different theoretical approaches are evidently in good agreement with each other. Other related physical quantities, collective mode frequencies and velocity of sound, as calculated using dynamical structure factors have also been reported.
