A complete photoionization experiment with polarized atoms using magnetic dichroism and phase tilt measurements

Abstract

The study of the $5p$ photoemission from laser polarized (aligned or oriented) Eu atoms was used to deduce the ratio of the magnitude of the electric dipole amplitudes and the phase difference between the two outgoing $\ensuremath{\epsilon}s$ and $\ensuremath{\epsilon}d$ electron waves. The combination of magnetic dichroism experiments, the measurement of the difference spectra for two atomic polarizations, and phase tilt experiments, the observation of the modulation of the photoelectron signal on the angle \ensuremath{\eta} of linear laser polarization, is a very promising method for performing a ``complete'' photoionization experiment.
