Resumen:
The relevance of the induced potential on photoelectron emission from metal surfaces for grazing incidence of ultra short laser pulses is studied. To describe this process we introduce a distorted wave-method, which includes the perturbation on the emitted electron produced by both the laser and the induced fields. The method is applied to an Al(111) surface and the results are compared with the numerical solution to the time-dependent Schrödinger equation (TDSE). We find that our approach reproduces well the main features of emission spectra, accounting properly for effects originated by the induced potential.
