We consider the generalization of Bijl-Feynman excitation energy formula to multi-component Bose fluids. Identification of these excitation energies with those obtained from the poles of the density-density response function simplifies the calculation of static structure factors Sij(q) . This in turn helps simplify the self-consistent calculations that go beyond the usual random-phase approximation. We illustrate our approach by evaluating the structure factors and local-field corrections in a double-layer charged Bose gas. © Tübi̇tak.
