Abstract
In the tunnel model, a
fluid is regarded as being composed of lines of molecules which move almost
one-dimensionally in lines or tunnels, the walls of which are formed by
neighbouring lines of molecules. This model has been used, with good success,
to describe the properties of classical hard spheres and classical simple
liquids. For quantum fluids the energy levels of a one-dimensional line of
molecules must be calculated. This has been done only for a system of hard
spheres. For more complicated systems the energy levels must be approximated.
In this paper the tunnel model is applied to liquid 4He
at absolute zero and to liquid H2. The lowest energy level has been
approximated and the hard-sphere energy levels are used to estimate the higher
energy levels. The agreement with experiment is generally good except in the
critical region.
