We evaluate the ground-state properties of a charged Bose gas at T=0 within the quantum version of the self-consistent field approximation of Singwi, Tosi, Land, and Sjölander. The dynamical nature of the local-field correction is retained to include dynamic correlation effects. The resulting static structure factor S(q) and the local-field factor G(q) exhibit properties not described by other mean-field theories.
