Abstract: We study the elementary-excitation spectrum of a system of bosons interacting with a spherical-shell potential function from a theory combining the advantages of the method of correlated-basis-function and canonical transformation. By fitting physical parameters with those of liquid helium four into our derived equations, the computed results agree reasonably well with the experimental ones obtained from neutron scattering.
