✦ Synopsis

In order to achieve a comprehensive model for the elementary excitations in liquid helium, we modify the original cell model of Matsubara and Matsuda. We avoid the lattice anisotropy, taking an amorphous arrangement for the sites, with f cc short-range order. We compare our results to the experimental data and examine the limitations of the model.
