Abstract

We have developed a method which gives a continuous representation of the excitation spectrum (energy vs. momentum) for superfluid helium as a function of temperature and density, using neutron scattering data1–3 to determine the behavior of the various parameters which describe the shape of the spectrum. We have applied this model spectrum to the calculation of various thermodynamic properties of the liquid.
