摘要：
The local density functional theory and the moment sum rule method are used to calculate the momentum dispersion of surface plasmons in simple metals represented by the stabilized-jellium model. The crystal lattice effects incorporated by this model are found to increase the plasmon frequency of high electron density metals for larger wave vector. Results for the stabilized jellium are compared with experimental data and previous jellium calculations performed by using the sum rule technique and/or the time-dependent local density approach.
