A new empirical structure factor for real liquids using internal pressure

摘要: Abstract Customarily structure factor S ( Q ) of a liquid is determined experimentally (by X-ray or neutron scattering methods) and used to derive the radial distribution function g r which obviously laborious costly procedure. In present paper, an equation for real fluids derived incorporates directly internal pressure, π i , based on fact that, hence hard-sphere fluid are similar. The positions principal maxima (PPM) correlate nicely with those adduced by experimental techniques condensed liquids metals. (X-ray neutron) experiment, refers momentum change incident beam. our study continues have same meaning in ‘hypothetical’ experiment.
