摘要
We present a theoretical many-body analysis of the electron-electron (e-e) inelastic damping rate Gamma of electron-like excitations in the Shockley surface state band of Ag(111). It takes into account ab initio band structures for both bulk and surface states. Gamma is found to increase more rapidly as a function of surface state energy E than previously reported, thus leading to an improved agreement with experimental data.
