A sharp feature in the charge-density excitation spectra of single-crystalMgB$_{2}$, displaying a remarkable cosine-like, periodic energy dispersion withmomentum transfer ($q$) along the $c^{*}$-axis, has been observed for the firsttime by high-resolution non-resonant inelastic x-ray scattering (NIXS).Time-dependent density-functional theory calculations show that the physicsunderlying the NIXS data is strong coupling between single-particle andcollective degrees of freedom, mediated by large crystal local-field effects.As a result, the small-$q$ collective mode residing in the single-particleexcitation gap of the B $\pi$ bands reappears periodically in higher Brillouinzones. The NIXS data thus embody a novel signature of the layered electronicstructure of MgB$_{2}$.Comment: 5 pages, 4 figures, submitted to PR
