摘要：

We present a new method for extracting the condensate fraction from deep inelastic neutron scattering studies of superfluid helium. This method employs a model for the momentum distribution that incorporates the known limiting behavior from many-body theories and takes into account final-state effects present in deep inelastic neutron scattering measurements. We apply this procedure to deep inelastic neutron scattering measurements of helium over a wide range of temperatures and densities in the superfluid, normal liquid, and solid phases.
