Abstract
Recent neutron inelastic scattering experiments on dense krypton gases are analyzed using a dynamical theory of simple fluids which includes the correct static susceptibilities but approximates the generalized wave-number- and frequency-dependent transport coefficients by the hard-sphere Enskog-theory values. The full width at half maximum of the dynamical structure factor is found to depend strongly on the thermal pressure coefficient, which is evaluated and discussed for a Lennard-Jones pair potential using the Kirkwood superposition approximation.Keywords
