摘要：

An analytic formula is derived for the lowest-order effects of an added layer of electron density on the d-parameters of the theory of jellium-surface electromagnetic fields. The formula provides a basis for understanding how the d-electrons near the surface of a noble metal modify its long-wavelength surface plasmon dispersion. Thus, it helps explain why the linear coefficient of surface plasmon dispersion is larger on Ag(001) than on Ag(111), and in the [001] than in the [110BAR] direction on Ag(110), and also why it is positive in all these cases.
