Ponderomotive scattering strongly affects photoelectron spectra in above-threshold ionization. We review experimental studies of intensity-dependent angular distributions and inelastic electron scattering that demonstrate how electrons may be scattered, accelerated, or decelerated by the laser beam after photoionization.
