A generalized pseudopotential for hard-sphere interaction is obtained, which is valid for all angular-momentum states. This pseudopotential is then used in the evaluation of both the ground-state energy and the excitation spectrum for a dilute Bose system of hard spheres. The calculated ground-state energy agrees with that obtained by others; the excitation spectrum obtained for liquid helium resembles the phonon-roton spectrum introduced by Landau. (auth)
