摘要：

A simple model is presented to estimate the low-energy electron mean free path in transition metals and to calculate its spin dependence. In this model, the electron-scattering rate is directly related to the number of holes in the d bands; its spin asymmetry is almost proportional to the spin magnetic moment. These quantities show a weak energy dependence from the vacuum level up to a few tens of eV above the metal Fermi level.
