Abstract
The pair correlation function obtained from the neutron diffraction data of Mozer, De Graaf, and Le Neindre, is given for liquid 4He at several thermodynamic states above and below the superfluid transition. A method for smoothly and accurately extrapolating the pair function into the limit of zero internuclear separation is considered. The pair function is computed from an approximation integral equation for the ground state wave function and compared to the experimental results.Keywords
