Their interpretation is proposed with a model based on the absolute-phase dependence of the trajectories of the photoelectrons that contribute to a given harmonic order. Generation of relativistic photoelectrons induced by excimer laser irradiation. This effect can be ascribed to the different phase of the stationary trajectories of the photoelectrons that contribute to a given harmonic order. In this case, photoelectrons are emitted from the lunar surface due to solar ultraviolet photons. The electron imager side can also be used to record photoionization cross sections, photoelectron energy and angular distributions.

The photoelectron spectrum of electron energies is continuous since actual light sources contain a spread of energies.

It is also possible to gain additional information by performing experiments to look at the energy of the liberated photoelectron in these experiments.

In this approximation the final state is described by a core hole in the atomic core level and an excited photoelectron.

The photoelectron subsequently causes the emission of secondary electrons through the process of impact ionization.

Regardless of the incident photon beam however, all photoelectron spectroscopy revolves around the general theme of surface analysis by measuring the ejected electrons.

The photoelectron spectrum of a molecule contains a series of peaks each corresponding to one valence-region molecular orbital energy level.

As the kinetic energies of the electrons ejected in different processes largely overlap, it is impossible to identify these processes using simple photoelectron spectrometry.
