A model for the radial distribution function in superfluid 4He
Description
Starting from the definition of structure factor of fluids as the Fourier transform of the radial distribution function, and adopting a model for the distribution function to take care of realistic situations in liquid 4He at low temperatures, it has been found that there is a decrease of spatial order in liquid 4He at low temperatures and also that the 'roton' gap in the excitation energy spectrum of liquid 4He decreases with increase in density in agreement with experimental observations.
