Theory of the surface charge pseudopotential for the hard-sphere potential ts developed. It is shown that the formulas known to be exact are obtained by the present method. The excitation energy spectrum of the Bose system is calculated, and is shown to have the nonmonotontc behavior similar to the roton spectrum in liquid He4. The dispersion formula for the sound velocity is calculated and compared with that derived by Landau and Khalatonikov.
