Abstract The dielectric function is often known in the optical limit (zero momentum) but knowledge away from zero momentum is required for the calculation of many physical properties, such as ion stopping and inelastic mean free path. We review the several extension schemes and compare the results with the available literature and investigate in particular the effect of the extension scheme on the calculated proton stopping for the case of Li.
