Large nondipole parameters with strong correlation effects in photoelectron angular distributions at kilo-electron-volt energies

Strong correlation in quadrupole photoionization amplitudes, along with strong correlation in dipole photoionization amplitudes, is found at keV photon energies. As a result, correlation is shown to profoundly influence the $E1\ensuremath{-}E2$ nondipole photoelectron angular distribution parameters... View More
